Grass temperature sensor

1.Grass temperature sensor product introduction

Grass temperature sensor is a non-contact temperature sensor for long-term monitoring of temperature changes on road surfaces, plant canopies, soil, snow and water.HW1 is an integrated Grass temperature sensor.The optical system and electronic circuits are integrated into the metal housing.The protective cover is easy to install and 90° adjustable bracket; to meet the installation and uninterrupted measurement under various outdoor conditions.

The interior of HW1 is composed of a thermopile and a thermistor.All objects are constantly emitting infrared radiation energy to the surrounding space.By measuring the infrared energy radiated by themselves, their surface temperature can be accurately measured.This is the principle of non-contact infrared temperature measurement.The infrared thermometer can completely avoid contacting the target, and calculate the surface temperature of the object by measuring the infrared radiation emitted by the target, which is its biggest advantage.
