HX711 Weight Sensor The HX711 is a precision 24-bit analog-to-digital converter (ADC) designed for weigh scales and industrial control applications. It is commonly used to interface with load cells, which are sensors used to measure weight or force. The HX711 load cell amplifier provides a stable and accurate digital output of the load cell’s signal, […]
Fine Dust Sensor (Particulate Matter – PM Sensor) The Fine Dust sensor, also known as a Particulate Matter (PM) sensor, is a device used to measure the concentration of fine particulate matter in the air. Fine particulate matter refers to tiny, airborne particles or droplets that can be inhaled into the respiratory system and can […]
The Ultrasonic Sensor is a device that uses ultrasonic sound waves to measure distance and/or detect an object. They are a type of proximity sensor that works on the principle of echolocation, similar to how bats and dolphins navigate in the dark. These sensors emit high-frequency sound waves (ultrasonic waves) that are beyond the range […]
A Negative Temperature Coefficient (NTC) temperature sensor is a type of resistor that exhibits a decrease in electrical resistance as its temperature increases. In other words, the resistance of an NTC thermistor decreases as the temperature rises, and it increases as the temperature decreases. This behavior makes NTC thermistors suitable for various temperature-sensing applications. From […]
The DHT11 is a low-cost, digital temperature and humidity sensor. It is commonly used in electronics projects and applications to measure temperature and relative humidity. The sensor consists of a capacitive humidity sensor and a thermistor to measure temperature. It provides digital output, making it relatively easy to interface with microcontrollers like the micro:bit. Temperature […]
