Goal[edit | edit source]
The goal is to develop a green house controller. This product will operate without a grid-connection and be capable of gathering necessary data from sensors and controlled devices defined by the end user.
Background[edit | edit source]
The Greenhouse Controller was a project developed by high-schoolers mentored by Mr. Sikes throughout 2017-2018. Their project goal was to have a functioning product turning peripherals on and off based on data received from sensors. The sensors used were temperature and humidity sensor and soil moisture sensor. They used some peripherals such as a lamp and a fan only for the purpose of testing and research development.
Specifications[edit | edit source]
- Inexpensive (<= $100)
- Power availability of 2A at 5V
- Off grid power duration (4 hours intermittent)
- Works sensors for humanity (temperature, soil moisture, soil temperature)
- Working controller devices including (relay)
- Temperature range (-20C to 50C)
- Portable <= (15cm x 15cm x 10.cm)
- Light Weight (<= 4.5kg)
Goals[edit | edit source]
- To find an alternative to charge the battery while it's connected to the solar panel.
- operating voltage and current.
- Building a prototype and testing it.
- Design an enclosure for the controller.
- Adding more buck converters to provide 3V and 5.5V and 12V to the power supply.
- Adding more peripherals.
