Sensors

This module contains information on how to set up an environmental sensor for behavior experiments

The sensor measures

• temperature
• humidity
• light

Components

1. BME280 sensor (temperature and humidity)
2. Photoresistor (light)
3. Arduino Uno
4. RaspberryPi

NOTE. A BMP280 sensor exists which does not measure humidity.

How to set up the sensor connections

Photoresistor

• 10kOhm resistor and photoresistor need to be connected in series
• The remaining pins are connected to 5V and GND.
• The series connected pins should be connected to A0

BME280

4 headers need to be connected: 5V, GND, SDI (A4) and SCK (A5).

Arduino board	Headers	Component
5V	VIN	BME280
NA	3V	BME280
GND	GND	BME280
A5	SCK	BME280
NA	SDO	BME280
A4	SDI	BME280
NA	CS	BME280
A0	PHR2/10kOhm	PHResist
5V	PHR1	PHResist
GND	10 kOhm	PHResist

TODO

• If the Arduino is not connected on ACM0, figure it out and change the port
