Switch module (two-step controller) for almost all sensors and detectors. The input can be connected to a wide variety of sensors, depending on the area of use. Suitable sensors: The sensors are preassembled with a 1 m lead, Western connectors and cable gland. Dew point sensor (condensation water monitor): Detects the risk of condensation before it occurs. Humidity monitor for bath/shower, external walls, chilled ceilings, shop windows, etc. Conductance sensor: For monitoring water quality (ion content) or fill level, as a foam sensor, etc. Room humidity sensor: With sintered protective cap for controlling the relative humidity in greenhouses, terrariums, bathrooms, switch cabinets, etc. Temperature sensor -40 to +80 °C. In a stainless steel sensor tube, diameter 6 x 30 mm, or as a pressure-resistant screw-in sensor with M10 thread. Light sensor 50 - 2000 Lux: Weather-resistant, for indoor and outdoor installation.
