[PSUBS-MAILIST] FW: O2 and CO2 sensors

[Jon Wallace via Personal_Submersibles]

 I opted for the following CO2 and O2 sensors.https://www.co2meter.com/collections/1-percent-co2-sensor/products/cozir-10000-ppm-co2-temperature-humidity-sensor
https://www.co2meter.com/collections/oxygen-sensors/products/25-percent-oxygen-sensor

I interface with both via Serial communication.  They will work with any microprocessor that has serial capability.  There's a project page that describes how to use them along with PCB gerber files and software.  http://www.psubs.org/community/projects/

 I use

https://www.co2meter.com/products/k-30-fr-co2-sensor

This is an inexpensive 0-10,000 ppm co2 sensor.  Interfaces with plc through analog voltage input module.  With my use on R300, they last about 5 years.

Just looking at old emails on sensors for O2 and CO2 to try and find best bangs for bucks.

With the advance of technology over the last 10 years what are regarded by P-Subbers as the best to buy these days?

Regards,

Hugh
