The S4H-TM-xx temperature sensor is fitted with an internal and external probe and with a 2m long cable. The sensor can be used as a simple temperature probe or as a thermostat with two adjustable temperature limits. Information about temperature is sent from the sensor to the cloud via Wi-Fi and the home AP at 15-min, 30-min, 1-hour, 2-hour or 4-hour intervals. In the thermostat mode, notifications are sent outside of the selected time intervals when the temperature falls below or exceeds the preset limit. Information on the cloud is sent to your smartphone, where you can display it using the Smart4house® application as a numeric value or in the form of a diagram. You can use your smartphone to set or change the display mode, message sending intervals or monitored temperature limits. The measuring range of the internal probe is from 0 to +50°C, and the external sensor range is from -30 to +50°C.
