The GSM SMS Environment Alarm WH-170 is special for remotely monitoring site temperature, humidity, power status through wireless GSM Network. When the temperature, humidity, power status exceed high threshold or low threshold value, it will send SMS alert or call to 6 preset mobile phone immediately.
It is an automation system. When the temperature, humidity, power alarm and normal, it can link to Realy1 output actions, this is very useful when the temperature exceed appointed value, need switch on the air-conditioning immediately, or when water overflow and need switch on the dryer.
A relay0 with dial-in or SMS remote control. Up to 200 tel. numbers can be authorized for it. Because calls are not answered dial-in control within GSM is free of charge. (it only checks the caller’s number and - if the number is authorized - responds with relay activation.) This can be used for parking latch control, GSM gate opener, remote control machine, etc.
A siren output.when Alarm occurrence,it will output for 30 seconds.
It can report site environment in interval.
Rechargeable Backup Battery ( Optional ) inside can last 6 hours.
