Sensors and peripheral

LDR (Light measuring)

Many of the Photons have an LDR sensor to measure and log the light situation in the room. We need a 10 kOhm resistor between de LDR and de GND.

Components

• 1x LDR
• 1x 10kOhm resistor

External links: http://www.instructables.com/id/How-to-Use-a-Light-Dependent-Resistor-LDR/

RGB LED strip (color LED light)

A 12V RGB LED strip is connected to a Photon which can be controlled over the internet. It is possible to control the color of the light of the strip. It is possible to turn LED on/off and to control (dim) the light brightness.

Components

• 3x TIP120 / 3x TIP31 / 3x ZTX689B
• 3x 100 Ohm , 220 Ohm Resistor
• 1x 12V adaptor
• 1x 12V -> 5V Polulu D24V10F5 (option)

White LED strip (white LED light)

A 12V LED strip is connected to a Photon which can be controlled over the internet. It is possible to turn LED on/off and to control (dim) the light brightness.

Components

• 3x TIP120 / 3x TIP31 / 3x ZTX689B
• 3x 100 Ohm , 220 Ohm Resistor
• 1x 12V adaptor

PIR (motion detection)

Several Photons have a PIR attached to sense motion. Upon motion it is possible to e.g. turn on a LED strip or send an alert.

Components

• 1x PIR
