SM1 soil temperature and humidity sensor
A high-frequency FDR principle soil moisture sensor, developed and manufactured for measuring the vertical section of soil moisture and soil temperature. The sensor is 30cm to 150cm long, with a soil moisture measurement point every 10cm and a soil moisture measurement point every 30cm. A 150cm long sensor can measure 15 layers of water content and 5 layers of soil temperature. The SDI-12 Pentax interface can be connected to any ADTU configured RTU with SDI-12 interface.
The SM1 soil moisture probe is very convenient to install and use, and provides soil moisture and temperature monitoring based on capacitance measurement.
Soil moisture and temperature are measured at different depths, a soil moisture probe is placed every 10 cm, and a temperature sensor is placed every 30 cm. Multi-layer moisture temperature integrated measurement, tubular shell, diameter Φ32mm, supports tubular and mud installation, easy and fast installation. Using SDI-12 communication protocol, simple wiring.
According to the length of the sensor, there are 30, 60, 90, 120 and 150 cm. Users can choose different lengths according to their needs.
A maximum of 5 temperature sensors are available. Their temperature sensors are located at 15 cm, one every 30 cm, so the others are at 45, 75, 105, and 135 cm, respectively.
The device uses the sdi-12 protocol and comes with a 5m cable.
