TH302 data logger is a low-power, multi-functional data collector, which is independently developed by our company. It integrates solar charge controller, polymer lithium battery, GPRS, GPS and other components. It is compatible with sensors with analog, switch, frequency, SDI-12, RS485 and many other signal outputs, and also can read the data of MODBUS RTU module. It can supply power to the sensor on demand, and has Bluetooth and the function of remote wireless transmission.

  TH302 supports 32 measurement variables, which can directly measure the real-time value, maximum value, minimum value, average value, period cumulative value and permanent cumulative value of each variable. The measurement interface includes 5 analog channels, 1 switch channel, 1 frequency channel, 1 SHT series temperature and humidity sensor digital measurement channel, 6 SDI-12 channels and 1 RS485 channel, and can be expanded when using MODBUS module if needed.

  TH302 has Bluetooth and GSM / GPRS transmission functions, and parameter setting and data acquisition via Bluetooth / TCP / SMS. The data logger has built-in solar charge controller and 20Ah polymer lithium battery, which effectively reduces the system’s operating cost.

  TH302 can be connected to a variety of sensors for measuring meteorological parameters, soil moisture and other index, and is widely used in agriculture, forestry, meteorology and other fields.
