This project implements a low-power temperature measurement solution with connectivity to a peer-to-peer client via Bluetooth Low Energy (BLE). The ADC calibration and startup are consolidated within ...

Firmware and hardware guide for an open-source, solar-powered agricultural sensor system based on the STM32 "Blue Pill" and a SIM800L GSM module. This project is designed for remote environmental ...

Abstract: Using the Proportional-Integral-Derivative (PID) control method and the STM32 microcontroller unit, a quick and high-accuracy temperature control system was built (MCU). The temperature ...

Abstract: The design of this paper is to solve the problems of poor stability and low control accuracy of traditional temperature control system in industry, agriculture and even daily life. This ...
