22 -The DMT01 is a (% style="color:blue" %)professional-grade wireless meat thermometer(%%) engineered for accurate, real-time temperature monitoring in commercial cooking environments. Ideal for restaurants, central kitchens, catering services, and food processing facilities, the DMT01 ensures consistent results across various cooking methods—including grilling, smoking, roasting, deep-frying, sous vide, baking, and more. Its precise monitoring helps improve cooking efficiency, ensure food safety, and meet HACCP compliance standards.
28 +The POM01-NB integrates (% style="color:blue" %)**NB-IoT wireless module**(%%), which sends signals to the cloud platform when triggering alarms or timed reports, and is suitable for remote monitoring scenarios with wide coverage and low power consumption.
23 23  
24 -The system consists of two components:
25 - - (% style="color:blue" %)Food-grade BLE High-Temperature Probe(%%) – A durable, high-heat resistant probe that measures internal food temperature during cooking.
26 - - (% style="color:blue" %)Charging Base with BLE & LoRaWAN Forwarder(%%) – This base not only charges the probe but also acts as a communication bridge. It receives temperature data from the BLE probe and transmits it via the LoRaWAN long-range wireless protocol to your IoT platform or monitoring system.
30 +The POM01-NB adopts optocoupler isolation technology to detect whether the (% style="color:blue" %)**220V**(%%) power supply is normal or not, and can set the (% style="color:blue" %)**180V**(%%) low voltage trigger threshold to start the alarm logic immediately when the voltage drops abnormally.
27 27  
28 -With its dual wireless support (BLE for close-range accuracy and LoRaWAN for long-range data transmission), the DMT01 is ideal for both home cooking enthusiasts and commercial kitchen environments seeking smart, connected temperature monitoring.
32 +The main power supply of POM01-NB is directly powered by (% style="color:blue" %)**220V AC**(%%), and the backup power can be seamlessly switched after a power failure, guaranteeing continuous operation for 30 days.
29 29  
34 +POM01-NB has a wide temperature operating range, and the battery supports cyclic charging and discharging, adapting to complex industrial environments.
35 +
36 +POM01-NB (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
37 +
38 +POM01-NB supports different uplink methods include (% style="color:blue" %)**TCP, MQTT, UDP, MQTTs or CoAP**(%%) for different application requirement. and Support Uplinks to various IoT Servers.
39 +
40 +POM01-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
