Save Your Food with Arduino Freezer Temperature Sensor
https://www.electronics-lab.com/save-food-arduino-freezer-temperature-sensor/
“Arduino Freezer Temperature Sensor” is an Arduino based project which works as an indicator to notify you when the freezer isn’t work properly. This project was created by “John Saunders”. To make this project, you will need these parts: Arduino Nano, most of other Arduino boards can be used. USB cable, to connect the Arduino […]
Rubidium Disciplined Atomic Clock
https://www.electronics-lab.com/rubidium-disciplined-atomic-clock/
Cameron Meredith build a real-time-clock module controlled by a rubidium frequency standard, and since it also includes a GPS clock he can track local time dilation effects by comparing the two. An I2C multiplexer board allows for more than one RTC module (Since these have a hard coded I2C address you can normally only use […]

Would you like to monitor all the devices connected to you LAN. Then you can do it using a Rasberry Pi Zero and a few LEDs. Like most people, we have tons of things connected via WiFi to our router. Be it AppleTVs, Rasberry PIs, Amazon Echos, weather stations, overhead airplane trackers, security cameras, etc. […]
Optomyography: A novel approach of detecting muscular signals using optical sensors
https://www.electronics-lab.com/optomyography-novel-approach-detecting-muscular-signals-using-optical-sensors/
Optomyography is a novel, non-invasive, non-contact optical method to measure muscular signals of the human body for diagnosing muscular disorders. It is also considered as an emerging technique for making better human-machine interfaces. Matt, Amrit, and Maneesh conducted an optomyogram experiment at Cornell University to sense the movement of fingers and wrist, and eventually to […]

Do you wonder how to build a personal weather station with data logging capability? Well, Jesus Echavarria, a electronic engineer and DIY hardware maker from Spain, has shared the details of his design of a very professional-looking, full-featured, and portable weather data recorder that is capable of recording ambient temperature, humidity, and light level into […]
Wireless temperature and humidity monitor for baby’s room
https://www.electronics-lab.com/wireless-temperature-humidity-monitor-babys-room/
This project describes a DIY wireless temperature and humidity monitor for kids’ or infant’s room using the Arduino platform, and inexpensive and easily available ASK transmitter/receiver modules. On the transmitting end, an Arduino nano senses the ambient room temperature and humidity using the DHT22 sensor and transmits the data to a receiving end Arduino over […]

Atmel SAMD21G Sensor Board
https://www.electronics-lab.com/atmel-samd21g-sensor-board/
Mike Rankin created this tiny sensor board with an ARM Cortex M0+ microcontroller and OLED display: It’s pretty tiny so a 4 layer board made the whole job easier. The top and bottom are pretty much dedicated for components, layer1 are tracks and power traces, layer2 is a ground plane. Mixing up an internal plane […]
