pickandplace.wordpress.com writes: I started with making the TMP102 temperature sensor work. Nothing to say in particular, it’s just an other I2C-small-package-sensor. Or rather SMBus, but apart from the minimum speed clock requirements on the SMBus, the two protocols are alike. Designing a simple and cheap temperature logger – [Link]
Portable GPS Data Logger
https://www.electronics-lab.com/portable-gps-data-logger/
elm-chan.org has build a portable GPS logger based on ATMega328 mcu: I have built a GPS Logger and it works very well to trace the drove route for two years. By the way, the navigation solution computed by GPS receiver itself has an excellent accuracy without DGPS because an intentional offset added by US goverment […]
ESP8266 + Attiny85 + DHT22 Temperature/Humidity Logger
https://www.electronics-lab.com/esp8266-attiny85-dht22-temperaturehumidity-logger/
by guibom @ github.com: Basic ESP8266 + Attiny85 + DHT22 Temperature and Humidity logger. I’ve made this to experiment a bit with the ESP8266 wifi module, and hopefully make a remote sensor that posts the data to my server. I wrote the code to work with both an atmega328 and a attiny85. The mcu sleeps in between […]
