Converts analog output from Gravity pH, ORP, or D.O. meter to PWM and voltage signal
Comes with four standoffs and screws
Designed to work exclusively with the Gravity line
Voltage input: 3.0 V - 5.0 V
Connector: Header pins
The Gravity Analog Isolator is designed to work exclusively with the Gravity line of low-cost embedded meters. These isolators remove all electrical interference coming from other probes or pumps in the same water you are testing. It converts the analog output from a Gravity pH, Gravity ORP, or Gravity D.O. meter to both, a PWM and a voltage signal.
The PWM signal can then be easily converted back to a noise-free reading. Because this isolator uses PWM, it can be connected to a micro-controller that does not have an ADC. The voltage signal converts the sensor value into 0 - 3 Volts, good for a micro-controller that does have an ADC.
Please note: A Raspberry Pi cannot accurately read PWM or analog voltage without a 3rd party hat.
