Sensors

Sensors, transmitters and probes that turn a physical variable into a signal for a data logger, a controller or a supervisory system. The subcategories sort the models by what they measure: temperature and humidity, gases, light and solar radiation, rainfall, wind, pressure, water and soil, current and voltage, among others.

There are sensors with analog current or voltage outputs and with digital outputs such as SDI-12 and Modbus RTU, as well as models that show the reading on their own display or in an app.
