Default value for maximum measurement distance is 4m, since HC-SR04 sensor can't measure reliably beyond that. However, if you are using another sensor or if you you don't care about distances larger ...

Connect a 4k7 Ω pull-up resistor between the 1-Wire data line and 5V power. Note this applies to the Arduino platform, for ESP32 and 8266 you'll need to adjust the resistor value accordingly. For ...

Abstract: This paper presents an ultra-low-power, widedynamic-range interface circuit for capacitive and resistive sensors. The circuit is implemented as a switched-capacitor circuit using ...

Abstract: A temperature sensor based on the thermal diffusivity of IC-grade silicon has a near-linear digital output, which is insensitive to both process spread and packaging stress. Its accuracy is ...
