A touch sensor, especially a capacitive touch sensor, has some surprisingly sophisticated electronics to detect a fingertip. Luckily, little capacitive touch sensor/switch modules are widely available ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Ever wanted to measure soil moisture? Common “soil moisture meter module arduino raspberry compatible free shipping” PCBs might deceive you with their ascetic looks. Today, [Raphael (@r… ...

The sensor forms an image and OpenCV detects the actual touch configuration. It appears you can use the raw data from the Arduino, too, but it might be a little harder.

Smart soil moisture-monitoring machine An amazing addition to your gardening toolkit Like the weather station, you’ll need a proper sensor for this project, namely a capacitive moisture sensor.

To take full advantage of the Touch Board's capacitive capabilities, a bit of "distance code" can be uploaded to the board, making the touch sensor sensitive enough that you can interact with it ...

Arduino Nano. Capacitive soil moisture sensor. Raspberry Pi 3. 5V solenoid water valve + relay. Workflow: Arduino checks moisture and sends readings to the Pi. A Python script on the Pi decides when ...
