DFRobot TS01 Infrared Temperature Sensor Module Technical Information
Overview
The DFRobot TS01 is a non-contact infrared (IR) temperature sensor module designed to measure the surface temperature of objects without physical contact.
Measurement range: 70C to 380C
Output: Analog voltage proportional to temperature
Type: Non-contact IR sensor
Ideal for temperature monitoring, industrial process control, and robotics applications.
Working Principle
Infrared Thermopile Sensing
Detects infrared radiation emitted by a surface
Thermopile converts IR radiation into voltage signal proportional to temperature
st the target
Generates a small voltage corresponding to energy absorbed
Internal amplifier converts voltage linear analog output
Microcontroller reads voltage converts to temperature
Measurement Characteristics
Temperature range: 70C to 380C
