d6t-2jcieev01-raspberrypi

It is a sample projects for D6T OMRON MEMS Thermal Sensors with evaluation kit 2JCIE-EV01-RP1 and some Raspberry Pi boards.

D6T sensor series are High Sensitivity Enables Detection of Stationary Human Presence,

• OMRON's unique MEMS and ASIC technology achieve a high SNR.
• Superior noise immunity with a digital output.
• High-precision area temperature detection with low cross-talk field of view characteristics

Description

this Raspberry Pi sample projects for acquiring data from sensors on 2JCIE-EV01. sample projects output the sensor data.

Installation

Prerequisite

• gcc (pre-installed in standard Raspbian)
• Required change I2C speed to 100kHz for D6T-1A/8L/44L (see below)

Procedure

this procedure shows the procedure to use the sensors on 2JCIE-EV01-RP1 .

1. download the archive from github releases or master

   $ unzip d6t-2jcieev01-raspberrypi-master.zip

   or, with git:

   $ git clone https://github.com/omron-devhub/d6t-2jcieev01-raspberrypi

2. make

   $ cd d6t-2jcieev01-raspberrypi-master
   $ make all

3. run

   $ ./d6t-1a

   $ ./d6t-8l

   $ ./d6t-8lh

   $ ./d6t-44l

   $ ./d6t-32l

Change I2C speed to 100kHz or less

1. edit /boot/config, find below string

dtparam=i2c_arm=on

2. change i2c speed: append the parameter ,i2c_arm_baudrate=n , /boot/config will be changed as below.

dtparam=i2c_arm=on,i2c_arm_baudrate=100000

3. Required ) then reboot
