The ESP8266 microcontroller is a favorite among makers for creating affordable, Wi-Fi-enabled sensor projects. Pairing it with a DHT22 temperature and humidity sensor is one of the easiest ways to get ...

Abstract: Due to increased demand in the biomedical equipment sector, need for gas consumption assessment systems is naturally growing. The purpose of this study is to obtain a model of a hot-wire gas ...

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 ...

Abstract: Structural health monitoring (SHM) using wireless sensor networks (WSNs) has gained research interest due to its ability to reduce the costs associated with the installation and maintenance ...

AM232X is a sensor similar to the DHT12 with an I2C interface. Although in theory this could enable multiple sensors on one bus the AM232X has a fixed address 0x5C so one need to implement a ...
