Every CPU hides a temperature sensor. Read it with one microcontroller, two wires and zero extra components.
Monitor Temperature and Humidity in realtime using ESP8266 NodeMCU and DHT11 sensor. The sensor readings are sent to the KiwisIoT dashboard.
Turn a XIAO ESP32-S3 into a USB to I2C bridge with Bit Pirate, then read an LPS22 by register name in your browser. No code.
DS18B20 thermostat with RC5 remote, EEPROM logger, and Bluetooth app
A joystick-driven Arduino UNO desk console for students: temperature, humidity, Pomodoro, dice, chess clock. Grove, no soldering.
Temperature, humidity, pressure and air quality on a 240x320 display: auto day/night dimming, history charts, alarms, JSON/CSV export.
WiFi sensor with Wemos D1 mini and AHT20 + BMP280 module, integrated in Home Assistant, in a parametric 3D printed case.
Smart Temperature and Humidity logger featuring the nRF52832 Development Kit.
A deterministic, 6-task FreeRTOS room monitoring system on the STM32F103C8T6 using STM32Cube HAL, Wokwi, Unity unit tests, and Cppcheck.
Monitor temperature and relative humidity remotely using a DHT11 sensor, NodeMCU ESP8266 and KiwisIoT.
A small 4-layer ESP32-S3 board with native USB-C, an ENS210 sensor and an RGB LED. Designed in KiCad 9, made by JLCPCB, worked first time.
