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.

In the case of working with an MCU:

VCC ↔ 3.3V ~ 5V

GND ↔ GND

SDA ↔ MCU.I2C data line

SCL ↔ MCU.I2C clock line

Application:

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

Features:

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.

Package Includes:

1 x Infrared Temperature Sensor
