## Description

Atlas Scientific EZO-pH Embedded pH Circuit .001-14: Ph Sensor: desertcart.com: Industrial & Scientific

Review: Works great - Works great. I had issues at first but it was due to not fully reading the datasheet. I could not get this ph circuit to function properly with the Raspberry Pi. Half of the time it would display incorrect results or not show at all. The device was being powered incorrectly because I had it plugged into the 5v and not the 3v pin on the raspberry pi. Hope this helps someone who runs into the same issue. After connecting it to the 3v pin, it functions flawlessy.
Review: Didn’t work with a pi zero - I was using a pi zero. First ph sensor I was able to put into i2c mode by following the online instructions by removing the ground wire to the sensor but the address failed to populate so I set it back to uart mode and was able to send a command. Then the sensor got hung up. It became unresponsive. Replacement came in but I was unable to power off the sensor by disconnecting ground to put into i2c mode. Sensor stayed powered on with just the vcc.

### ⭐⭐⭐⭐⭐ Super easy pH probe interface, high build quality and accurate!
*by B***H on December 4, 2017*

Using this interface board is really a no-brainer. Atlas has really made accurate reading of pH probes so simple with this board. I use this board with an Atlas pH probe and it's interfaced to a Raspberry Pi 3 Model B using I2C for communications. I can't say enough good things regarding Atlas or their equipment. Use this pH board and probe if you want accurate, easy, painless pH data in your projects!
