ThermaLink-32 schematic using an ESP32 DevKitC V4 with IR transmit/receive, DHT22, HC-SR501, and push-button inputs for a JLCPCB 2-layer design.

The main board for UbiHouse Mini. Controlling 2 DC motors, 1 LED, 2 RGB LED, 1 humidity and temperature sensor (DHT22), 1 water level sensor with a ESP32 S3 Mini

This is the circuitry for the smart inhaler project. This utilises an HC-05 as well as a DHT22 alongside the STM32 and a LiPo battery.

Temperature indicator using an Arduino Uno, a 16x2 I2C LCD, and a DHT22 temperature and humidity sensor, with minimal supporting components for pull-up and power stabilization.
