HAPI Overview
The HAPI system is based on low cost micro-controllers providing sufficient computing power to monitor and control all local production resources. These resources are comprised of the sensors that monitor the environment and growing conditions, and the controls that affect these conditions. The results of these activities are published using a standard messaging protocol called MQTT. The information that is published can then be used to analyse the conditions, monitor the controls, and change the operation of the system.
Release 1 of the HAPI system uses Raspberry Pi Zeros (HAPiZ) as the Smart Modules that run the system code, the sensor code and the control code. Multiples HAPiZ devices can exist within the system and collaborate to determine the tasks performed by each module.
A minimum HAPiZ module consists of a Raspberry Pi Zero, a real-time-clock (DS3231), a temperature and humidity sensor (DHT22) and a water temperature sensor (DS18B20).
