Wireless sensor array -

Nov 25, 2011· If heat in the regulators is a concern, reduce the input supply voltage. Don't go lower than 6V or the CO2 sensor might get into trouble. The external power supply should maintain 6V at 550 mA output current. I'ld increase the CO2 modules decoupling substantially (100 uF close to the pins if possible) and make sure the power trace is wide.
