Moisture Sensor Project with GrovePi and Hologram Nova This project uses the Grove Moisture Sensor that can be used to detect the moisture of the soil or there exists water around the sensor. The sensor can just simply be inserted into the a plant’s soil and measure the moisture in the soil. Based on the data, it is possible to determine if the soil is humid or dry and it can send a notification ‘Feed me some water’ to the owner of the plant. This project shows how to use a cellular modem purpose built for IoT development from Hologram to send alerts/notifications.
