== 1.1 What is DMT01 Wireless Meat Thermometer ==

20

21

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.

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.

27

28

With its dual wireless support ((% style="color:blue" %)BLE for close-range/small design(%%) and (% style="color:blue" %)LoRaWAN for long-range data transmission(%%)), the DMT01 is ideal for both home cooking enthusiasts and commercial kitchen environments seeking smart, connected temperature monitoring.

== 1.2 Features ==

* Wireless Meat Thermometer – Designed for accurate and reliable cooking temperature monitoring

33

* Food-Grade Probe – Safe for food contact and dishwasher-compatible for easy cleaning

34

* BLE 5.1 Broadcasting – Supports real-time local data transmission via Bluetooth Low Energy

35

* LoRaWAN Connectivity – Enables long-range, low-power data transmission to IoT platforms

(((

DMT01 Include two parts,

150

151

1. The food grade probe : used to measure the meat temperature

152

1. The Charger which is also a LoRaWAN End node: used to connect the probe via BLE and get the temperature and send via LoRaWAN to IoT server.

Consider the BLE coverage , there is two cases:

157

158

=== **Connection Mode: Probe is near by the Charge, within BLE range** ===

159

160

Probe will establish connection to the charge via BLE. and the data flow is as below.

164

165

166

=== **Broadcast Mode: Probe is far away from the Charge, out of BLE range** ===

167

168

Probe will auto swtich to BLE broadcast mode and broadcast the data via BLE. Any BLE Scaner can pick up the signal and send to IoT server.

For example:

1) User can use BH01 BLE to LoRaWAN converter to pick up the BLE signal to IoT Server

173

174

2) User can use Mobile phone to get the broadcast signal and further process.

175

176

177

== 2.2 Activate Device ==

178

179

To use DMT01 send data to LoRaWAN network, user need to:

180

181

1. Input the OTAA Keys in LoRaWAN Network Server

182

1. Make sure there is LoraWAN network

183

1. Press the button on the DMT01 for more than 3 seconds, DMT01 will start to connect to LoRaWAN network

After the DMT01 Join LoRaWAN network, once user take out the probe, the probe will start to measure temperature and user will be to see the data on the server.
