Watcher Jet is a set of an Arduino, a RaspberryPi Zero W and some Electorinc components with an internal UPS, to make sure the whole hardware and software of an Industrial monitoring application will work seamlessly
-
Wathcer jet heart is to make collabration between Arduino and RPI to have better data consitency
-
Order the PCB and the BOM of Watcher and solder all components on the board
-
USE Arduino IDE to upload the jet-arduino into the arduino board
-
Install the Raspberry Pi Imager
-
Download and extract the lite image
-
in the OS customisation Config page,set the name like
2024031501
(time + cronical number); set the user and password of rpi, the default user ispi
and the default password israspberry
; the ssid and the password of the wireless network (i.e.monitait
andp@assword
) and in the SERVICES tab, enable theSSH
(follow the instruction below)
- Put the SD card in the RPI and wait for the RPI finish the setup
- ssh into rpi
ssh pi@2024031501
sudo apt-get install git -y
cd ~
git clone https://github.com/virasad/monitait_watcher_jet.git
bash /home/pi/monitait_watcher_jet/init/init.sh
sudo reboot now
What spare parts are needed to run on the watcher
- An SD card
- An external 12.6v 2A for
PS
(to recharfe the internal battries, a regulated 12.6v power is needed) - An Access Point with a SSID like:
monitait
and a password like:p@ssword
- a 12-24V digital signal for
OK
- a 12-24V digital signal for
NG
- a 4-20mA analog signal for
C
- a USB camera for
CAMERA
- a mini HDMI for
HDMI
- the polarity only is important for PS
there is a register id for each watcher, add the register id in monitait console Watchers tab
- by sending Signals you should see blue indicators blink
- if the counting reached half of acceptable threshold, the warning red indicator will be turn on (in case of low battery as well)
- if the link between watcher and the server established, the link inidactor blinks
