Passive wireless temperature sensor

(passive)

Sensor structure:

① Electrical alloy sheet: used for induction electrical collection

② Back cover: sensing temperature

③ Soft silicone: deepen the connection strength

④ Connection head: the connection takes a single piece double head

⑤ Screw: fix the cable

Install

Miniature passive wireless temperature sensor

Step 2: Insert the strip and the soft silicone into the sensor (the corrugated side of the soft silicone faces down in line with the sensing temperature position)

Step 3: Wrap the module around the electrical part (current main circuit) so that the temperature measuring point touches the temperature measuring part, and tighten the alloy sheet on both sides, and overlap the two ends of the electrical piece under the buckle。
