Feature

●PERIODIC REMINDER: The temperature humidity alarm can be set to automatically report the current status to the first user number at a fixed time every day or periodically, with smart chip, reliable to use.
●Temperature setting: the upper and lower alarm limits of the temperature can be adjusted according to the actual application. As soon as the current value reaches the alarm value, an alarm SMS is sent and a call is made to notify the user.
●SMS reminder: The ambient monitoring alarm supports 10 authorized user numbers that can receive alarm SMS when alarming, the last 5 authorised numbers can also receive telephone alarm reminders.
●Real-time monitoring: support for Modbus RTU via TCP and for the Modbus TCP protocol, can connect to the cloud platform for real-time monitoring via the network. The built-in battery can continue working for 8 hours in the event of a power cut.
●Current Status Question: Users can call the device number through the authorized number, the device rejects automatically and immediately sends the current status SMS to the call, users can also check the current status by SMS command.
