[contest] BcSensor

[AlinClaudiu]

Hi,
i attached my sensors boards
the are 2 versions, one for battery power and one for Wall Adapter Power Supply
The battery powered version:
-is connected directly to the battery

• 2x connectors for Dallas temperature sensor
• 1 - photocell (light sensor)
  (this version is reporting the battery level)
  
  

The other version (Wall Adapter Power Supply)

• 2x connectors for Dallas temperature sensor
• 1 - photocell connector (light sensor)
• 1 DHT-22 connector (humidity and temperature)
• 1 connector for pir sensor (HC-SR501 PIR Motion Sensor Module)
• 1 connector for PWM IRF3205 (led light controller )
• 1 conenctor for Magnetic Door Switch Sensor
• 1 conenctor for power out (5v)
  (this version has a 1117 3.3v regulator and 7805 5.0v)
  

**the 3rd version has a relay instead of IRF3205 **

all my sensors are connected to an MQTT gateway what is powered by my switching power regulator (5v , 2x 3v3)

the mqtt gateway is connected to the controller rasbperry pi

• (working with openhab and pidome [not at the same time])

here is the for for one of my sensors

how do you make these pcb so beautiful?

my pcb are full of wires !!!

[AlinClaudiu]

@gigi
traditional method, with iron , ferric chloride ..etc
and after etching i use Rothenberger Rosol 3 before drilling

[epierre]

@AlinClaudiu What kind of batteries are you using and what are the average life and ways to use less power ?

[AlinClaudiu]

@epierre Lipo battery 950mah, for now has 1 month and is not depleted, I just disconnected the power led and use mysensors sleep
