Hi everyone.
There something I need you guys to help.
I am working on air quality meansurement system.
The sensors I used are Co2 sensor, O2 senor, barometer, gps, leds, buzzer and xbee.
I connected all these sensors to Arduino uno and everything works well when i plug this to computer.
However when i used the battery that i have attached in the image, it cant work at all.
Can anyone help me? I really need you to help as this project deadline is coming.
Thanks
Liting
What attachment? What image? What battery? How is the battery connected? What is the voltage and current rating of the battery?
LEDs are not usually sensors.
Buzzers are not usually sensors.
XBee is a brand name, not a sensor.
okie. haha. I using Xbee S2.
The battery i used is Li-Pol 4400mAh, 3.7 battery. it is connected using solar charger shield.
Please show your wiring and provide a link to the solar charger shield. A 3.7 volt battery will not power an Uno unless there is an upconverter.
