5 Volts 1-Channel relay module, 2-channel and 4-channel relay module are an interfacing boards that is compatible with Arduino, AVR, PIC, ARM, RPi boards etc. It controls larger loads and devices like DC motors, AC motors, and other AC- DC devices with the digital outputs from controllers and processors. It is frequently used in the automatic control circuit. To put it simply, it is a mechanical switch to controlling a high-current circuit with a low-current signal.

  • It can control high-load current, which can reach 240V, 10A (AC&DC).
  • Fast switching.
  • On-board power LED indicator.
  • Available with both normally open (NO) and normally closed (NC)

IR Sensor Module

The IR Sensor (Infrared Obstacle detector) Module an I.R. sensor can measure the heat of an object as well as detect motion. These sensors measure just infrared radiation instead of emanating it, which is known as a passive I.R. sensor. The onboard comparator (LM358) circuitry does the processing and the green LED indicator lights up. The module out[puts a 3 pin interface with Vcc, GND, and an OUTPUT pin via male jumpers. The emitter is simply an IR LED (Light Emitting Diode). The detector is merely an I.R. photodiode sensitive to I.R. light of the same wavelength as that emitted by the IR LED. When infrared light strikes the photodiode, the output voltages vary in response.

  • Easy to use.
  • Onboard detection led indicator.
  • The effective distance range of 2cm to 80cm.
  • The detection distance can be adjusted with potentiometer.
  • The comparator using LM358, stable.
  • We can use a 3-5 Volt D.C. power supply module.
  • The red power LED is lit when power is ON.
  • Each module has a threshold comparator voltage adjustable via potentiometer.
  • If there is an obstacle, the led turns on the circuit board.
