Thus, they entered a heart rate sensor to our 2025 One Hertz Challenge! The build is based around a Wemos D1 mini, a ESP8266 development board.

The DHT20 is a humidity and temperature sensor. The sensor has a fixed address of 0x38. It is not known if the address can be changed. The library must be initiated by calling the begin () function.

SparkFun Humidity Sensor - SHTC3 (Qwiic) This Arduino library allows you to take Humidity and Temperature readings using the SHTC3 sensor from Sensirion using the standard Wire (I2C) library built ...

Accurate ocean temperature measurement is critical for climate studies and ocean circulation modeling. Thermistor-based sensors, valued for high sensitivity and stability, require precise calibration ...

This paper presents a CMOS temperature sensor intended for the temperature compensation of MEMS frequency references. It is based on a Wien bridge RC filter, whose phase-shift, due to the temperature ...
