Sensors are where projects meet the real world — and where most wiring mistakes happen. These guides cover the popular modules (BME280, MPU6050, DHT22, ultrasonic, and dozens more) with pinouts, working code for Arduino, ESP32, and Pi, plus the calibration tricks that turn noisy readings into trustworthy data. All the featured sensors ship pre-soldered below.
