Growing house controllers

MM3D programmable growing house controlling and remote monitoring device

The device is capable of measuring, controlling and monitoring the characteristics of a growing site.

Supply voltage:5V DC (with 230 V AC/5 V DC adapter)
Supply current:max. 2,5 A
Isolation class:II. class
Mechanical size:190x140x70 mm
IP protection:IP 54
IK protection:IK 03
Cover:termoplast (ABS)
LAN:Ethernet (RJ45)

The device is based on a Raspberry Pi 3 B + microcomputer with Raspbian operating system, which also includes software for operating the unit. No graphics system installed on it. Input and output peripherals and error LEDs have no predetermined function and can be programmed by the user.

The device's four TTL-level inputs are equipped with pull-up resistors and have an active level of L. They can be used, for example, to check the position of air vents, doors and windows, check the functioning of the ventilation system (airflow sensor), the water pressure sensor, or the status of the motor or overcurrent protection devices with auxiliary contact.

There is no need to connect a keyboard or monitor to set up and operate the MM3D, and access to it is always done through SSH. Current status and measured data can be checked using a web browser. project page
