Abstract: This brief introduces a current calibration circuit that is specifically designed for use in a column-parallel Dual-Ramp Single-Slope (DRSS) ADC. This circuit creates two current sources ...
DHT11 and DHT22 are two popular sensors among microcontroller users, especially the cheap DHT11s. DHT22s cost more but have better data resolution. My codes are based on MonadnockSystems/pxt-dht11 but ...
