NDA required. The device will be 8" Long x 2" Deep x 2" Height It is a timer actuated by the removal of an object on the surface of device. When object is placed on device, timer starts. When object is removed, timer stops and resets. There are four independent timers on this 8" long device. Each 2" x 2". So, place the object on the device and led illuminates red. Timer starts. When timer reaches interval, LED illuminates green. This indicates the timer has reached the set interval. When object is removed from device, the LED turns off. When device is placed back on device, timer starts over and LED illuminates red. A small button in bottom left of 2x2 square can reset timer as if the object was removed. Intervals can be adjusted from 1 minute to 72 hours with a sliding bar. Each of the four timers can be adjusted independently. Low battery indicator light required. Power on/off required. Need the electronics for above device including PCB, schematic, LED, battery, etc. Need the enclosure design and all mechanical

@Anakie

You need to explain what you are aiming to do - is this a prototype of something? Microprocessors are nice but have inherent problems with product development that the uninitiated don't get Relevant Skills and Experience Over 25 years of Automation and Control Systems Engineering Open a chat so I can get an idea of what you are doing. Proposed Milestones $5 USD - These are just Questions and observations - no fees no obligations $5 USD - IR sensors can cost from a few $$ to hundreds what have you looked at so far $5 USD - Microprocessors and custom boards can be very expensive to produce the first one $5 USD - Using sliders and pots for adjusting anything (like timers) is very inaccurate and unreliable $5 USD - You actually need a proper technical specification for this $5 USD - Give me a separate Freelancer project for $30 and I will write you a proper specification $220 USD - That way you can get any of the Arduino guys to deliver you a working prototype for about $100 Open a chat so I can explain why a specification will help you - no obligation
