Temperature Humidity Alarm GSM 3G 4G Sensitive Accurate Power Failure Alarm Set with Sensor

Feature: 1. Temperature Humidity Sensor: The digital temperature and humidity module is a temperature and humidity composite sensor with calibrated digital signal output and supports for RTU Over TCP and for TCP protocols. 2. Network Communication: The host adopts GSM, 3G, 4G network communication, which is not limited by distance and can be used anywhere. 3. Voltage Detection: The host has a built in microprocessor to monitor the voltage value of the power supply, so there is no need to purchase a professional monitoring voltage probe, saving costs. 4. Automatic Reporting: Users can set the daily fixed point or periodically automatically report the current status to the first user number, and can remotely query the alarm history via SMS. 5. Humanized Design: The alarm supports 10 authorized user numbers, which can receive alarm SMS when alarming, and the last 5 authorized numbers can also receive alarm call reminders.
