What is it?

This is a "simple" tiny op-amp buffer designed to buffer Plessey EPIC sensor input to an ADC. It is a summing amplifier to convert a -3.3-3.3V (provided by an outside bipolar power supply) swing output from the EPIC Sensor to 0-3.3V that is compatible with most common ADC. In addition, it provides a 3rd Order Sallen-Key low pass filter at 1KHz (~200Hz in latest design) to help remove some harmonics. In addition, it provides a -50dB twin T notch filter that lowers the 50Hz and 60Hz AC noise inherent to indoors use. This is a compromise to the passive component arrays in production as well as multinational function.

This board is experimental and additional components and filtering may be required for a good signal.

It does not come with sensors. They must be purchased separately (Plessey EPIC Contact Sensors or the Plessey EPIC Contactless Sensors).

Why did you make it?

Fyber Labs is experimenting with Plessey EPIC sensors and required decent buffering of their output. We recommend utilizing it with the Plessey EPIC Contact Sensors or the Plessey EPIC Contactless Sensors. 4 channels are available, but 2-3 should be only required depending on sensor configuration.

What makes it special?

There are no other break out boards available to buffer Plessey EPIC sensors.
