GSM Temperature Monitoring Alarm
GSM 3G 4G LTE Temperature Monitoring Alarm
The GSM 3G 4G LTE Temperature Monitoring Alarm is special for remotely monitoring onsite temperature, power status through wireless GSM/3G/4G Network. When the temperature, power voltage exceed high threshold or low threshold value, will send SMS alert to upto 10 preset mobile phone immediately,It supports Modbus TCP and Modbus RTU Over TCP,can be integrated to Cloud Platform.
Mainly Features of 4G Temperature Monitoring Alarm:
1. Can be operated from anywhere, no distance limitation;
2. No call charges for inquiry. the GSM 3G 4G LTE Temperature Monitoring Alarm rejects the call from authorized number then return onsite temperature and power voltage on the first ‘ring’;
3. Multiple applications. (temperature, power status, solar panel, dc voltage);
4. Up to 10 authorized phone numbers, 5 can be used to receive call or SMS,and 5 can be used to call and SMS while alarm occurrence;
5. One DS18B20 temperature sensor input, measures temperatures from -55-+125°C,0.5°C accuracy from -10-+85°C;
6. External AC Power status monitoring, AC On/OFF will send SMS to authorized phone numbers;
7. Inbuilt MCU monitoring the DC input Voltage value, measure range is 9-24VDC, no need additional sensor to save cost;
8. Timer Report—Can setup every x hours automatically send its status/Value to the authorized numbers;
9. Support remotely read historic data via SMS;
10. Support Modbus TCP and Modbus RTU Over TCP protocol for cloud monitoring;
11. Rechargeable Backup Battery inside can last 8hours;
12. Secure – Using caller ID and password for identification, unknown callers are ignored;
13. Programmable by SMS Commands or APPs with password protection;
14. Based on GSM/3G/4G Network, applied to many applications.
15. Remote Reset via SMS, Remote Reboot via SMS, Automatic Reboot Periodicity.
