Gravity Analog Isolator

Description

• Gravity Analog Isolator
• 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.
