Product Introduction

The Bluetooth Temperature and Vibration Module - MTV4.0 is based on wireless Bluetooth BLE5.1 communication, using the high-precision programmable digital temperature series chips (T117B, etc.) independently developed by Minyuan. It includes high-precision three-axis MEMS gravity acceleration and temperature sensing, can output three-dimensional acceleration and temperature information, and embeds FFT frequency domain analysis. Mobile phones or other Bluetooth devices communicate with the module to read and display measurement data, then upload to the cloud platform. It can be widely used in wireless temperature measurement, wearables, cold chain logistics, and other fields.
