2 IN 1 soil temperature and humidity sensor moisture RS485 modubs voltage 0-2V 0-5V 0-10V current 4-20MA 0-20MA | Инструменты

T: temperature

H:humidity

for example :T and H with 4-20ma  means the product can measure temerature and humidty with 4-20ma output

Soil moisture sensor, soil temperature sensor, soil temperature and humidity sensor (voltage type (0-2V, 0.4-2V), current type (0-20mA,4-20mA), Type 485)

Equipped with 3 meters long

Soil moisture sensors are based on dielectric theory and have been independently developed using frequency-domain measurement techniques to accurately measure the volumetric moisture content of soil and other porous media. It can be integrated with systems such as greenhouse environmental monitoring, soil moisture collection, and automatic irrigation control to achieve long-term continuous dynamic monitoring of moisture.
