Water Tank Overflow Alarm System Using ESP8266
https://www.electronics-lab.com/esp8266-overflow-alarm-system/
Sometimes the float valve of a water tank may not work properly causing water to overflow and spread across the floor. Peter Jennings faced this problem in his storage area, and he had developed an alarm device to notify him when the water exceeds its normal range. Peter’s project includes a simple water sensor and […]

DIY Arduino ProMini Data Logger
https://www.electronics-lab.com/diy-arduino-promini-data-logger/
Ed Mallon has details on his DIY ProMini data logger: Typical pro-mini loggers built with this design sleep at 0.25mA, before extra sensors are added. At that current draw, the logger should deliver approximately six months of operation on three brand new AA batteries with a 15min duty cycle; depending on sensor load. DIY Arduino […]
