Feature:

. Used to remotely monitor the temperature, humidity and power status of the site through the wireless GSM networks. When the temperature, humidity, and power status exceed the high or low threshold, it will immediately send SMS reminders or call 6 preset mobile phones.
2. It is an automation system. When the temperature, humidity, power alarm and normal, it can link to Realy 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.
3. 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 control, GSM gate opener, remote control machine, etc.
4. Alarm output, when an alarm occurs, it will output for 30 seconds. It can report the site environment at intervals.
5. It can be operated anywhere, there is no distance limit. The internal rechargeable backup battery (not included) can be used for 6 hours.
6. Up to 200 authorized phone numbers. The st ‑3rd user numbers can receive SMS, and the 4th ‑6th user numbers can receive call while alarm occurrence. ‑200 authorized phone numbers can call T200 to turn on/off the Relay0 free of charge.
7. temperature and humidity sensor input, temperature measurement range: ‑40‑80°C, accuracy: 0.5°C. Humidity measurement range: 0‑99%, accuracy: 3%.
8. External AC/DC power status monitoring, AC/DC power on/off will immediately send SMS and call 6 preset mobile phones.
9. Timer report‑can setup every x hours automatically send its status/value to 6 preset mobile phone immediately.
0. Support remote reading of historical data via SMS. It can be programmed via SMS commands with password protection.
. Using caller ID and password for identification, unknown callers are ignored, secure to use.
2. Based on the GSM networks, it is suitable for many applications. (Temperature, humidity, power status, solar panels, DC voltage).
