Aperture: 3mm Wiring Instructions: DAT: digital output interface VCC: 5V DC power supply positive GND: 5V DC power supply negative Package Included: 4 X Infrared transmitter module 4 X Infrared receiver module Review: Works great as long as you have the right expectations - These are good, cheap IR boards. As other reviewers have noted, the VCC lead on the transmitter isn't actually connected to anything; it's just part of the pin header. The transmitter is just an IR LED and a resistor; the DATA pin is really the + line, so if you send it current there, it turns on. You simply bit-bang on that pin to send pulses. If you're using something like a Raspberry Pi, you won't get great range, because all of the GPIO pins are 3.3 volts. I'm using it to control an A/V receiver and have the LED right next to the panel, so it works great. If you need more range, though, you'll want to hook it up to the 5v rail via a transistor and probably also surround it with an IR reflector (as-packaged, it's an omnidirectional LED). The IR receiver works just like you'd expect, and obviously it _does_ need power, so all three pins are needed: data, vcc (5 volt, although might work with 3.3; I didn't test that), and ground. I believe data is pulled high and drops to ground when a signal is received. If you're using a Raspberry Pi with a reasonably current OS, you don't need to download any drivers; much of what you see online is old. Add the appropriate lines ("dtoverlay=gpio-ir,gpio_pin=" and "dtoverlay=gpio-ir-tx,gpio_pin=") to /boot/config.txt (or /boot/firmware/config.txt if running Debian 12). Note that, if you are going to both send AND receive (i.e. you have both lines in the config file and you've hooked up both boards), you'll need to specify which device to use (--device=) in the ir-ctl command: one will be /dev/lirc0 and the other will be /dev/lirc1; this is why some of the reviewers couldn't do both at the same time. Simply use the 'ir-ctl' command to send and receive pulses. ir-ctl can read to and write from a file, so to train it, just set it to write to a file, and then you can play those exact commands back by reading from the same. Review: Receiver works great; transmitter is terrible - Receiver is fine since you can shove a remote right up to it to get it payload from. However, the 220Ohm resistor on the transmitter module makes them nearly useless; you can replace with 91Ohm resistor (just note how tiny these are; 1206 is about my limit, and these resistors are even smaller; this was a frustrating experience) for better range. You could also solder bridge if you're only going to be dealing with short pulses. Note if you solder bridge, you are likely to burn out the LED eventually. Even with a solder bridge, though, the transmitter's range is quite poor. It does at least become usable without taping the board with the transmitter to the device you want to control, though; now you can be nearly 2 feet away! Given the price, I won't be *too* harsh on it, but this is definitely a "you get what you pay for" situation. If you're looking to build a universal remote for your devices, keep looking or build your own. ## Features - The infrared transmitter module is directly transmitted by a single tube, and the waveform needs to be modulated by the program. - Adopt 1838 remote control receiver with high sensitivity. - with the emission signal indicator LED, easy to observe and debug. - Can be used for remoter control,Can be compatible with wrobot digital 38KHz IR transmitter sensor. - Widely used in infrared communication, infrared remote control, apply to a variety of platforms including Arduino/Raspberry pi/51/AVR/ARM. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08X2MFS6S | | Additional Features | Ergonomic | | Brand | DORHEA | | Button Quantity | 3 | | Color | 8PCS | | Colour | 8PCS | | Compatible Devices | Raspberry pi, 51, AVR, ARM | | Compatible devices | Raspberry pi, 51, AVR, ARM | | Connectivity Technology | Infrared | | Connectivity technology | Infrared | | Controller Type | Button Control | | Customer Reviews | 4.3 out of 5 stars 92 Reviews | | Manufacturer | DORHEA | | Max number of supported devices | 8 | | Maximum Number of Supported Devices | 8 | | Maximum Range | 1.3 Meters | | Model Name | 13658-1 | | Model Number | 13658-1 | | Special features | Ergonomic | | UPC | 701715461482 | | Unit Count | 8.0 Count | ## Product Details - **Brand:** DORHEA - **Special features:** Ergonomic - **Colour:** 8PCS - **Compatible devices:** Raspberry pi, 51, AVR, ARM - **Connectivity technology:** Infrared ## Images ![Dorhea 4Pcs Digital 38khz Ir Receiver Sensor Module + 4Pcs 38khz Ir Transmitter Sensor Module Kit for Ardu ino Electronic Building Block - Image 1](https://m.media-amazon.com/images/I/71Nv9fNOdgL.jpg) ![Dorhea 4Pcs Digital 38khz Ir Receiver Sensor Module + 4Pcs 38khz Ir Transmitter Sensor Module Kit for Ardu ino Electronic Building Block - Image 2](https://m.media-amazon.com/images/I/71M387+4huL.jpg) ![Dorhea 4Pcs Digital 38khz Ir Receiver Sensor Module + 4Pcs 38khz Ir Transmitter Sensor Module Kit for Ardu ino Electronic Building Block - Image 3](https://m.media-amazon.com/images/I/71T5MguunhL.jpg) ![Dorhea 4Pcs Digital 38khz Ir Receiver Sensor Module + 4Pcs 38khz Ir Transmitter Sensor Module Kit for Ardu ino Electronic Building Block - Image 4](https://m.media-amazon.com/images/I/51OIQofqy5L.jpg) ![Dorhea 4Pcs Digital 38khz Ir Receiver Sensor Module + 4Pcs 38khz Ir Transmitter Sensor Module Kit for Ardu ino Electronic Building Block - Image 5](https://m.media-amazon.com/images/I/51b9jXCyTCL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great as long as you have the right expectations *by T***R on 20 May 2024* These are good, cheap IR boards.

However, the 220Ohm resistor on the transmitter module makes them nearly useless; you can replace with 91Ohm resistor (just note how tiny these are; 1206 is about my limit, and these resistors are even smaller; this was a frustrating experience) for better range.

If you're looking to build a universal remote for your devices, keep looking or build your own. ### ⭐⭐⭐⭐⭐ Transmitter and receiver work fine on Raspberry Pi Zero W *by A***N on 6 October 2021* I use these on a Raspberry Pi Zero W for a very specific purpose: to monitor if kodi is playing and when it stops playing, turns the TV off (because I have a tendency to fall asleep). My TV doesn't support the power off signal via HDMI, so I had to make something work the old IR way. I did struggle a bit getting it setup, but in the end, I got it. I hooked up the transmitter to 5v and receiver to 3v and used GPIO pins for signal. I couldn't use both receiver and transmitter at the same time, the pi only wants one or the other enabled in /boot/config.txt, but for my purposes that was fine. I loaded the receiver to record the IR signal, then once I had it, I disabled it and enabled the transmitter to send that signal. Good thing to know here: the pin #s it wants are the GPIO numbers, NOT the pin numbers. Once I got that sorted I was good. I can't speak to how well it does with distance, since I have the pi stashed behind the TV and the transmitter sticking out just far enough for the TV to be able to pick it up. Overall I'm happy, the price was good and it works for my need. ## Frequently Bought Together - Dorhea 4Pcs Digital 38khz Ir Receiver Sensor Module + 4Pcs 38khz Ir Transmitter Sensor Module Kit for Electronic Building Block - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - Gikfun Infrared Diode Led IR Emission and Receiver for Arduino (Pack of 10 Pairs) EK8460 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/485638389-dorhea-4pcs-digital-38khz-ir-receiver-sensor-module-4pcs-38khz](https://www.desertcart.in/products/485638389-dorhea-4pcs-digital-38khz-ir-receiver-sensor-module-4pcs-38khz) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-07-09*
