Temp.measured in my garden. Mean of 3 sensors. DIY solar powered NodeMCU.
This is my first IoT channel to test how ThingSpeak works.
Wemos D1 Mini TCP server with Dallas ds18b20 sampling temperatures updating via TCP over local in each location Raspberry Pi5 calls for temperature every 30 minutes (crontab), writes to a MySQL database and sends to Thingspeak.
Data collection from Raspberry Pi: includes temperature, turbidity, COTS detection, and pressure.
This channel monitors and logs real-time freezer temperature using a DS18B20 sensor and ESP32. Safety levels are indicated using LEDs and data is sent every second via MQTT.
I made a simple weather station for my room using an ESP32 and a BME680 sensor. It keeps track of the temperature, humidity, and pressure so I can monitor how comfy (or not) my room is, especially when I have the aircon or fan on.
Two temperatures probes turn the attic fan on when outside temperature is significantly lower than the inside temperature.
This channel collects environmental data such as soil moisture, temperature, and humidity for agricultural monitoring and analysis.
