The Waveshare Contact-less Infrared Temperature Sensor is an Infra-Red thermometer for non-contact temperature measurements. Both the IR-sensitive thermopile detector chip and the signal conditioning ASSP are integrated into the same TO-39 can.

Thanks to its low noise amplifier, 17-bit ADC, and powerful DSP unit, high accuracy, and resolution of the thermometer is achieved.

The thermometer comes factory calibrated with a digital PWM and SMBus (System Management Bus) output. As a standard, the 10-bit PWM is configured to continuously transmit the measured temperature in the range of -20…120˚C, with an output resolution of 0.14˚C.

Waveshare Contact-Less Infrared Temperature Sensor

In the case of working with an MCU:

VCC ↔ 3.3V ~ 5V


SDA ↔ MCU.I2C data line

SCL ↔ MCU.I2C clock line

  1. High-precision contact-less temperature measurement
  2. Industrial temperature control
  3. Household appliances temperature control

For Software setup, please follow this tutorial.


  1. Measures the surface temperature of an object without touching it, depending on the emitted IR waves of the target.
  2. Also measures the average temperature over an area.
  3. Contact-less, high precision, high resolution, fast response.
  4. Calibrated before delivery, with gradient temperature compensation.
  5. Works with 3.3V/5V MCU system directly, thanks to the built-in level translation.
