DetectIR – advanced IR receiver modules


Choose one of the configuration options below. We use only high quality IR components from Vishay. (Contact us in advance if you require non-standard IR receivers configured)


DetectIR –  is an advanced module for receiving and detecting/testing modulated Infrared signals for interfacing to a microcontroller or operating stand-alone as a visual detector/tester. DetectIR allows makers, hobbyists and professionals to incorporate infrared receiver & detection functionality into their projects using quality IR components and excellent design features. DetectIR can operate standalone or integrated into existing projects and provides excellent reception range and signal quality for both 3V3 and 5V systems. It can be powered directly from a microcontroller, USB ports, batteries or via stand-alone power supplies connected to the PCB headers.

Available Options

  • IR receiver – Select any standard IR carrier frequency and we will configure & test the module using high Quality Vishay receivers.

  • IR Detector/Tester – We will configure the module as an IR detector/tester. In this mode the module provides a visual indicator of modulated IR remote control signals from 20-60kHz, which can be useful during installs or product development for assessing operation and to some degree range/angle of operation.
  • Custom configuration – for a small additional fee we can configure a wider range of receivers into the module. Contact us first with your requirements & use case. To support this offering  we have included multiple footprints for the most common IR receivers. The module has both through hole and SMD footptints available for each component.
  • DIY assembly – we can provide a DIY kit with any of the standard receivers. You will then have to solder the components to the PCB (NB: Soldering skills & equipment required) See Bulk orders below.
  • PCB only – you can order one or more PCBs and provide and populate your own components. (NB: Soldering skills & equipment required)

What is DetectIR ?

DetectIR is made up of 3 components:

  • The DetectIR board module with integrated high quality IR receiver, which can provide a range of functionality from Visual detection, remote control and serial data transfer (rx only).
  • A power supply provided via the microcontroller or via an independent DC power source or battery. (Not Included.)
  • The included high quality IR receiver (Included) can be mounted on-board or located remotely via cabling (Not Included).

DetectIR is an excellent companion device for any 5V or 3V3 project and can operate from 3V3 to 5.5V supplies (Max 6V). When operating as a visual detector/tester it is configured with a visual indicator and can operate from 2 AA batteries for 2-3 months, drawing just under 0.8mA of idle current (1 year+ when used with on/off switch).

DetectIR provides the leading operating range and when configured as a serial data receiver the highest baud rate in its class (details over).

What’s Included

Each DetectIR module is configured with a choice of high quality IR receivers or detectors to match the intended function. You can opt to have the receivers and header pins soldered or not. Test points and spare positions are not populated, by default.
Configuration Options include one of the following per module:

  • IR Receiver: 30,33,36,38,40 or 56kHz and subject to availability 455kHz
  • IR Detector/Tester: optimised for 30-60kHz modulated IR signals
  • Serial over IR: 4,800 (continuous), 9600(non-continuous) when fed directly to UART and up to 7,800bps (continuous) using custom encoding/firmware.

A quick-start guide is provided after purchase which covers: pin-outs, headers, , 5v/3V3 operating modes and Test Points for better understanding of the circuit and trouble shooting.    See Product Sheet for more details!
