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.
