€15 IoT Geiger Counter using ESP8266
https://www.electronics-lab.com/e15-iot-geiger-counter-using-esp8266/
Geiger counters are devices used to detect radioactive emissions, most commonly beta particles and gamma rays. The counter consists of a tube filled with an inert gas that becomes conductive of electricity when it is impacted by a high-energy particle. The Geiger–Müller tube or G–M tube is the sensing element of the Geiger counter instrument […]

Turn your Zero Pi into a USB Dongle
https://www.electronics-lab.com/turn-zero-pi-usb-dongle/
The $5 Raspberry Pi Zero is a standalone computer that can be embedded in various applications, but maybe now it is time to add some extra features. It comes with a USB OTG port, meaning it can function as a USB device rather than a USB host. Thus, it can become a serial device with […]
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 […]
PWM Fan controller
https://www.electronics-lab.com/pwm-fan-controller/
Lucky Resistor has build a PWM fan controller using Arduino and DHT22 sesnsors. The fan controller described on this project page, controls one or more PWM controlled 12V PC fans. It uses the input from two precise DHT22 based temperature sensors. The MCU is an Arduino Uno, which is powered using a 12V power source. […]
How to Choose a Connector
https://www.electronics-lab.com/how-to-choose-a-connector/
Sanket Gupta @ octopart.com discuss on how to choose a connector. He writes: Continuing our series about choosing parts, inspired by the latest version of the Common Parts Library, let’s take a close look at how to find and select connectors. In this blog, we will explain all the different types of connectors, their merits and demerits, […]
Pressure sensors need as little as 0.9 V
https://www.electronics-lab.com/pressure-sensors-need-little-0-9-v/
Susan Nordyk@ edn.com: These micropower low-pressure sensors operate from a supply voltage of just 0.9 V to 1.8 V and are intended for use with noncorrosive, nonionic working fluids in such applications as medical devices and instrumentation, environmental controls, HVAC equipment, and portable devices. Pressure sensors need as little as 0.9 V – [Link]
