We completed the sensors! We have tested the two modules for the temperature and humidity sensor and the vibration sensors in the lab.

We can use the ESP32 Vroom with the development board and also the Xiao ESP32 C3 with Seeedstudio development board (which comes complete with SD card, Oled, RTC and BMS built in). The temperature sensor is developed with the Xiao ecosystem and has been integrated with MQTT. The data is published by Adafruit.IO.

Current codes are being prepared for Github.

Overall design of the sensors. For testing in the lab, the module is powered by two 18650 batteries through a barrel powerjack of the development board. The vibration module uses SW-420 module encapsulated in a round plastic container.

Other components linked to the module are the microSD, RTC and LCD screen. All these modules are connected using I2C connection.

This is a field test deployment of the module at Chagar Hutang. The module is placed in a weather-proof box container (holes for the wires are sealed with glue reinforced with resin to prevent water leakage). We use a D4 Solar Panel Charger built in 18650 battery 4w Mini Solar Power Charger 6v output as the power supply.
