Características Sensor de Temperatura do Solo

  • Low cost
  • No need to calibrate.
  • Rugged design for long term use. 
  • Small size. 
  • Consumes less than 3mA for very low power operation.
  • Precise measurement.
  • Output Voltage is linear to temperature. 
  • No complex Steinhart-Hart equations are needed to convert voltage to temperature. 
  • Wide supply voltage range. 
  • Can be buried and is water proof. 
  • Probe is long and slender for wider use, including smaller potted plants.

The THERM200 is a soil temperature probe, which has a temperature span from -40°C to 85°C.  It outputs a voltage linearly proportional to the temperature, so no complex equations are required, to calculate the temperature from voltage.  It is highly accurate with 0.125°C of resolution.

The sensor has a simple 3 wire interface: ground, power, and output,  and  is powered from 3.6V to 20VDC, and outputs a voltage 0 to 3V. Where 0 represents -40°C and 3V represents 85°.

The probes can be buried, or inserted into pots. Since the blade is so narrow, it can easily be inserted into potted plants.    

The temperature sensor can be used with our soil moisture sensors, and together they can be used to detect the presence of ice.  

The THERM200 is compatible with our data Loggers, or  any other third-party data logger. 

O sensor de temperatura pode ser usado com a humidade do solo VH400 sensores, e podem ser usados em conjunto para detectar a presença de gelo.

Thermistor based temperature sensors, are typically inaccurate, and use the complex Steinhart-Hart equation which contains complex calculations such as logarithmic and third order terms, which are difficult for microcontrollers to compute. 

Once you've tried the THERM200, you'll never want to use a thermistor based sensor again.
