Wireless m-bus sensor for ambient temperature and humidity

Wireless m-bus sensor TH-1

TH-1 sensor is intended to measure ambient temperature and humidity. Data is transmitted via wireless m-bus protocol, mode T1 (OMS compatible). Temperature is measured and transmitted in degrees Celsius, with precision of 0.1 degrees C. Humidity is percentage, with precision of 1 percent. The sensor transmits every minute a T1 telegram with current instantenous data. Telegrams by default are not encrypted and follow the OMS standard, which makes the sensor easy to be read by any compatible wireless m-bus reader. Device works on battery, calculated for approximately 12 years of work (with transmission period of 60 seconds). TH-1 is just a plug-and-play sensor, but of course can be ordered with different transmission period and/or encryption (AES-128, Mode5). Intended for mounting on a wall (or any flat surface), hidden screws and small dimensions. The enclosure is elegant and small, giving many opportunities for mounting. The enclosure itself is with IP68, but due to cutting holes for incoming air we do not recommend this sensor for outdoor mounting. There is an option TH-1 to measure also CO2 (THC-1), but for more information on this topic please contact us.
