U3121M 物聯網無線溫度和相對濕度數據記錄儀，用於外部探頭，內置2G調制解調器
U3121M
The GSM DataCORDER is designed to record temperature and humidity from an external probe.
If the set limits are exceeded, SMS and JSON messages can be sent via the GPRS data connection. The measured values can be sent to the internet storage COMET Cloud, which is a complete monitoring, alarming and analyzing system.
It can also be set to send JSON messages to the COMET database at adjustable intervals. Alarms can also be displayed locally via LEDs, LCDs and a built-in buzzer.
Recording takes place in a non-volatile electronic memory. Data can be transferred to a computer via the included USB-C cable.
Temperature and humidity probes are not included in the delivery, you can choose the appropriate length and design of the probe from the optional accessories.
