Abstract: This paper describes a ZigBee-based wireless sensor network node for the ultraviolet (UV) detection of flame. The sensor node is composed of a ZnSSe UV photodetector, a current-sensitive ...

Thermal printing is a non-impact printing method that uses heat to produce images or text on specially coated heat-sensitive paper, known as thermal paper. It prints by passing the thermal paper over ...

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 ...

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 ...
