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 […]
Air pressure sensors in smartphones
https://www.electronics-lab.com/air-pressure-sensors-smartphones/
Dr. Thomas Block has a great article about air pressure measurement on smartphones and which benefits this may have. Today’s smartphones utilize a wide array of accelerometers, gyroscopes and various other sensors in their designs. Relatively unknown is the barometric pressure sensor, which measures air pressure. These sensors are currently being integrated into premium-grade smartphones, […]
