Hi.
Can anyone help with the best way to convert the square wave signal to a dc voltage between 0v and 5v.
I've attached the datasheet for reference.
I'm trying to integrate this sensor into a old circuit that uses accelerometers that is like a voltage divider and sends the signal through a few op amps. When the sensor is flat it gives out a steady 2.5v moving it to either side will make the voltage either go up or down

Low-pass filter the outputs - what bandwidth / response time are you looking for?
On the datasheet it says its 100hz. Response time needs to be more or less instantaneous

That's not the response time, that's the PWM frequency. Since this is a thermal device it may be quite
slow.
"more or less instantaneous" - could mean 1µs, 1ms, 1s or 100s, depending on your expectations.
Numbers please, not adjectives.
I'd be thinking 100ms should be fast enough response
