The TSM400-1-TH is a humidity and temperature sensor that supports the MODBUS RTU protocol over the RS-485 interface. A unique capacitive element is used to measure relative humidity, while temperature is measured by a bandgap sensor. Both sensors are seamlessly connected to a 12-bit analog to digital converter. This results in superior signal quality. The TSM400-1-TH multisensor is housed in a slim plastic housing. The lower part of the cabinet is suitable for mounting on standard ø68mm built-in/cavity wall boxes, with installation openings of 61 mm.
