Atlas Sensors

You'll need to replace the placeholder values for ssid, password, channelId, and writeAPIKey with the appropriate values for your ThingSpeak channel. Also, you'll need to install the necessary libraries for the pH sensor and ThingSpeak, such as Adafruit_MCP9808, WiYou'll need to replace the placeholder values for ssid, password, channelId, and writeAPIKey with the appropriate values for your ThingSpeak channel. Also, you'll need to install the necessary libraries for the pH sensor and ThingSpeak, such as Adafruit_MCP9808, WiFi, and ThingSpeak.

This is a basic example and you may need to adjust the code based on your specific sensor and wiring.Fi, and ThingSpeak.
