Simple battery options for mysensors

[Matt Pitts]

Hi, I've just started putting together my sensor network based on all the very helpful info here. I'm planning to follow the my sensor guides as closely as possible, unless people have other suggestions.

I'm struggling to find a simple guide to battery powering senors. I'm sure this subject has been done many times before.

I would like to put sensors in the garden and in various locations around the house and batteries are an obvious solution. However I'm unclear about which is the best and longest lasting battery option for temperature sensor, door and motion sensors.

I was planning to base them on either a ardino nano or the newer wifi modules, however I'm assuming the wifi will use far more power that the NRF24L01+ 2.4GHz Wireless Transceiver based sensors.

I'm a complete beginner at this, so I'm looking for simple step by step guides.

I would really appreciate some help and best practice recommendations. I obviously would like to build something self contained and as small as possible with the longest battery life. I'm guessing this is a fairly normal requirement. Any help would be very much appreciated from more experienced people here.

Just search for microbender - its sketch has been adopted for a battery run

@alexsh1 Did you mean the Sensebender Micro?

@m26872 - sorry, yes I meant Sensebender
