This project builds a practical wireless temperature monitoring system using two Arduino UNO boards. One Arduino reads temperature from a DS18B20 sensor and sends it wirelessly through a 433 MHz RF ...
The DS18B20 is a digital temperature sensor from Dallas Semiconductors, which is now part of Maxim (https://datasheets.maximintegrated.com/en/ds/DS18B20.pdf). The ...
This repo supports only the DS18B20, other sensors have not yet been tested. You can feel free to do so. You will need a pull-up resistor, i used a 5K ohm resistor. Alter code to use up to 18 sensors.
Wi-Fi機能付きのマイコン「RaspberryPi Pico W(ラズパイピコW) 」で、防水型の温度センサ「DS18B20」を使う方法を解説してます。 今年は記録的な猛暑らしく、家庭菜園や花壇、子供が遊ぶお庭など、外の暑さが何かと気になりますよね。 DIYのネタにしてみようかな?
