Analog Input Issue

Sensors
1

Hi Everyone
Does anyone know if a high Analog Input affects the sensor in any way? Mine sits at around 4.3-4.7V and all the other sensors around me sit at 0.0V. Is this a problem & will it affect the sensors performance or lifespan?

Thank You

Hi @Me912

There is nothing to be concerned about. Only some newer PurpleAir devices are capable of reporting Voltage to the map. This is due to a hardware change we’ve implemented on more recent Flex and Zen devices. Most deployed sensors aren’t capable of properly reporting their voltage and in reality, most PurpleAir devices are going to be at 4 - 5V connection as we recommend 5Vs for devices.
