We’re looking for a product developer / engineer who can help us build a simple and low cost CO2 controller for horticultural applications. The controller should be made from parts readily available and easy to manufacture. The person we’re looking for is experienced with product / industrial design and engineering. Preferably you also have experience with product sourcing and making prototypes. If we both like the relationship we have multiple products that need design/engineering, so this could be something ongoing. In your PM, please tell us your experiences and training. More details are available true PM.

Hello, Im a British electronics design engineer with 35 years design experience. I have PMB a snippet of my resume that is relevant to your project. I would like to know more details about the product you require. I take it the unit will have a co2 sensor and operate an electro mechanical valve for co2 release, the valve being controlled against co2 levels in the atmosphere? Regards Ray
