1. Overview
This manual explains how to use the Arduino (*1) compatible OMRON Sensor Evaluation Board
(2JCIE-EV01-AR1), including special notes and other information. This Sensor Evaluation Board
provides 6 sensing functions (temperature, humidity, barometric pressure, illumination, sound,
acceleration). This manual explains how to acquire these sensing data.
To connect a sensor other than the 6 types of sensors provided on the Sensor Evaluation Board, check
GitHub. For details on the provided sensor types, connector layout, and other specifications, see the
data sheet for this product.
2. Items required
Sensor Evaluation Board (2JCIE-EV01-AR1) x1
Arduino (*1) x1
USB cable (to connect Arduino to your PC) x1
PC with Arduino IDE (*2) installed x1
(*1) Usable Arduino types
Arduino MKR Vidor 4000
Arduino MKR WiFi 1010
Arduino MKR ZERO
(This manual assumes that Arduino MKR WiFi 1010 is used)
(*2)
Arduino IDE can be downloaded for free from the official Arduino website.

3. Sensor board setup
3-1 Checking Sensor Evaluation Board Components
Make sure the following components are included with the Sensor Evaluation Board.
Sensor Evaluation Board x1
Pin Headers x2

3-2 Soldering
1) From the back of the Sensor Evaluation Board, insert the provided pin header into the
through-holes (CN10, CN11). We recommend that you use a breadboard to keep the pin header
from shifting out of position.

Fig. 2 Appearance of Sensor Evaluation Board
Note:
This side with the printed OMRON logo is the front side.
If soldering fails and you need to purchase a pin header, purchase a pin header with 14 pins at a
pitch of 2.54 mm.
Recommended pin Header: SAMTEC / TSW-114-07-L-S

2) Solder all pins from the front side of the Sensor Evaluation Board to secure them. (28 pins)
Fig. 3 Pin Header Soldering
Note:
Take care not to burn yourself when soldering.
Take care not to inhale smoke when soldering.
The pin header bends easily. Take care not to bend the pin header.

3-3 Connecting the Sensor Evaluation Board to Arduino
Insert the pin header on the Sensor Evaluation Board into the Arduino pin socket. The Sensor
Evaluation Board is on top and Arduino is on the bottom.
Fig. 4 Connecting to Arduino
Note:
The temperature sensor on the Sensor Evaluation Board may output a high value due to heat from the
Arduino unit. To eliminate this effect, either connect with a cable to separate the two, or use an
externally connected temperature/humidity sensor.
3-4 Connecting Arduino to your PC
Connect the USB port on Arduino to a USB port on your PC with a USB (A -micro B) cable.
