Wireless Temperature Alarm,Wireless Humidity Alarm,GSM SMS Alarm
Model: RTU5023
The GSM 3G SMS Environment Alarm is special for remotely monitoring onsite temperature, humidity, power status through wireless GSM/3G Network. When the temperature, humidity,
power voltage exceed high threshold or low threshold value, will send SMS alert to upto 10 preset mobile phone immediately.
Just dial from Authorized User number, the GSM 3G Environment Alarm will reject at the first “Ring”, no communication cost, and then return the current temperature, humidity, power status
or voltage. Moreover, it can report onsite environment interval or daily.
The GSM 3G Environment Alarm can be used for solar power monitoring, DC power voltage monitoring, temperature monitoring, humidity monitoring, Class Room, Public Room, Waiting Room,
Hospital, Stations, Fresh Food Warehouse, Office, Meeting Room, Laboratory, Library and anywhere that need monitoring temperature or control temperature in expected range.
