Hi All,
My company is interested in developing passive sensors that are capable of harnessing energy from the environment, so basically the sensor are completely dead and without power until there's either light, temperature difference, vibration, or RF illumination. So I do not care about high current draw in sleep mode. In this type of environmentwhat would work best? MSP430FR? or M0+?
Current draw during start-up on the MSP430 is also a problem, which is roughly 1 ms. Looking at the EMF32 Zero Gecko, Its list as 400us with a 24MHz clock. It seems to me that Zero Gecko would be a better choice, but from uA/MHz FRAM based MSP430 is a better choice.
I don't need to do any crazy computation here, all I need is for the ADC to measure a time decay, and send it back out through a wireless tx module.
