Hi,
I’m an Electronics Newby
The Situation
I want to make oxygen sensors for use inside sealed enclosures.
Each sensor is required to detect 02 levels (in air) to 0%, so the O2 levels can be stabilised to 3% or less using chemical scavengers. (Not a vacuum).
The Issue
There maybe between 1-12 sealed enclosures. I hope to use as many sensor units as required, but only 1 receiver/display unit.
The sensors (& their sender unit) would be placed in the sealed enclosures that may be difficult to see, so the receiver/display unit would have to be outside the enclosure. To prevent any leaks the sensor/sender units and the receiver/display unit cannot be hard wired, so either wifi, Bluetooth or another type of connection is essential.
The sensors must be self powered for up to a week.
There is WiFi in the lab already that could be connected to.
The Solution?
I imagine a Gravity I2C Oxygen Sensor hard connected to its own Arduino that has an integrated WiFi, and a separate display screen with its own WiFi that can show the O2 percentages. Will that work?
Will the receiver unit need it’s own Arduino too?
Your step by step help is GREATLY appreciated!
