The Helloplant sensor is designed to address the main reasons for dying plants: over or under watering, temperature, and light issues. A waterproof device that is inserted into the soil of a plant, it automatically measures soil moisture, ambient temperature, light intensity, and humidity, and can store several years of a plant’s vitals history.
Using Bluetooth, it will automatically connect to a user’s iOS or Android smartphone and send notifications when needed. According to the company, it proactively notifies users when to water their plant, and by how much, provides fertilizer reminders, and assists plant owners in finding the optimum physical location for their plant.
Measuring about 5.9 x 1.2 in., the device includes a precision capacitive soil moisture sensor, two temperature sensors for measuring upper and lower soil layers, and an ambient light sensor. It has a battery life of over a year and is designed to be used both indoors and outdoors. An optional Wi-Fi hub is available if remote access is needed.
Currently the project’s Kickstarter campaign is almost halfway funded towards its $35,638 goal with 30 days left.
