||Part # TEN-T3
|A fast and easy way to read multiple sensors with a Raspberry Pi.
The Tentacle T3 eliminates the requirement for wiring, multiplexing and electrical insulation. Because it comes in a Raspberry Pi HAT form, you can easily connect it to your Raspberry Pi.
No wiring, no breadboards. It is stackable and can accommodate up to 5 Atlas EZO devices.
measuring: PH, dissolved oxygen, electrical conductivity (EC), Oxidation-Reduction Potential (ORP) temperature (RTD), peristaltic pump (EZO-PMP), EZO-CO2 , EZO-RGB color sensor, EZO-PRS (pressure sensor.
The Tentacle T3 offers you 2 fully isolated channels for EZO circuits made by Atlas Scientific.
Channel 3 is perfect for adding RTD temperature compensation to your isolated channels.
With two additional channels you can connect Atlas Scientific 5-pin devices with a Molex connector.
These channels can also be used as general additional I2C connectors.
Channels 1 and 2 are fully isolated.
Built-in electrical isolation means that sensors will not interfere with each other and that most of the external electrical noise that can become the measurements is observed.
According to specification, Raspberry HATs cannot be stacked. That is why we do not call the Tentacle HAT.
You can stack Multiple tentacle T3 boards on your Pi.
Stack another, normally non-stackable HAT on top of the Tentacle.
You can easily stack 2 pieces to get a total of 4 isolated channels and 10 channels!
If you have a powerful PSU and want to mess with the pull-up resistors on board, you can stack even more.
The tentacle does not occupy raspberry pins.
It is connected to 5V, 3.3V, GND, SCL, SDA.
The tentacle adds pullup resistors to the I2C line, so you don't have to build them in yourself.
If your I2C pullup is processed somewhere else in your system, you can desolder these resistors from the tentacle.
