Industrial IR Non-Contact Grid 16x4 Temperature Sensor

The main function of this TC01 non-contact 16x4 pixel infrared temperature sensor is to realize remote temperature detection via non-contact 16x4 pixel infrared. It can detect the environment temperature, and its 16x4 pixels support producing temperature figure of 64 pixels. The sensor adopts metal crust, which is waterproof, dustproof and ensures high anti-interference even in varieties of complex scenarios. The standard Modbus-RTU industrial protocol RS485 interface is adopted. So that it is compatible with a variety of industrial personal computer.

It can be widely applied to applications like high-precision contactless temperature testing, temperature scanners, intrusion/motion detection, status detection/human positioning and so on.
