Another illustration that demonstrate how to wire the ESP32-WROOM set as client talk to ThingSpeak API. As you can see the diagram below, we will be going to build a non-contact temperature sensor using MLX90614. Unlike DHTXX, LMXX, HDCXX, HTUXX,
HTU21D is a digital humidity sensor with temperature output that uses MEAS (Measurement Specialties), the chip has embedded in a reflow solderable Dual flat leads (DFN) package with a size of 3X3X0.9MM. The HTU21D provides a calibrated linearized signal in
Here is another guide working with the HDC2080 high accuracy digital temperature & humidity sensor developed by Texas Instruments. The HDC2080 is an integrated humidity/temperature sensor the provides a high accuracy sensing acquisition with very low power consumption in a
The SENSIRION SDP3X family sensors comes with deferential pressure range of (500Pa, 125Pa) on i2c and analog in a small package. suitable for high-volume applications where size is required on a design project. The SDP3X family ideal for measuring of
BME280 is an integrated digital humidity, pressure and temperature sensor. This sensor module is compact in a small smart integrated device on a metal-led this device runs on a low power consumption that allow the sensor driven in a battery
This is the Silicon Labs Si7021 i2C Humidity / Temperature Sensor. Si7021 is a monolithic CMOS IC that integrates humidity / temperature sensor elements this device has an analog to digital converter, signal processing, calibration data, and an i2C interface.
In this illustration we will going to wire the DS18B20 single wire temperature sensor. The digital DS18B20 Sensor provide fairly good accuracy and range of connection. The wire length can be reach up to 100m. The DS18B20 has four main
