Design of a Smart Agricultural Greenhouse Environmental Control System Based on STM32
2026-10-24
A smart agricultural greenhouse environmental control system built on the STM32F103C8T6: DHT11 and BH1750 sample temperature, humidity and light, five hysteresis-based automatic rules drive the fan, heater, humidifier and grow light, and two configurable timing windows support overnight spans. Thresholds are persisted with CRC16 protection, while an ESP12F exposes an HTTP+JSON API paired with a React Native mobile app.
Design of a Grain-Storage Intelligent Ventilation System Based on STM32

A grain-storage intelligent ventilation system built on STM32F103C8T6 and ESP12F: a DS18B20 probe buried in the grain bulk measures grain temperature, DHT11 humidity interlock prevents moisture damage, gear-based target-differential control drives the fan, and a React Native mobile app provides LAN-direct control, scheduled ventilation, and runtime data curves.
