Power Consumption Calculation for xbee 900
First we calculate our battery The battery is rated at 3.7v @ 200 mA to make it easier to convert later we turn it into micro volts. To calculate the Watt hours = voltage * Amps 740,000 micro watt hours = 3.7volts * 200,000 micro amp hours Now we Calculate the xbee 900 which run ...
RF Radios
My group and I were testing these RF Radios to see if we can make some DIY rfids. These modules are 434 mhz radio transmitter and receiver pairs that run at a range from 2v – 12v. It operates at 2400 baud rate. For more information is located on the sparkfun site: transmitter and receiver. ...
Wildlife Tracking: RFID research
So I was interested in RFID for tracking monkeys. RFID comes in two flavors: passive and active. For tracking monkeys the preferable would be an active RFID chip. Active vs Passive Active Power: Battery powered, average 7000 hrs *depending on receiver Signal Strength needed: Low Signal Range: up to 100m Data Storage: 128kb read/write search and ...
Wildlife/People Observation
We went to Coles gym to observe people playing basketball. Tracking targets that move fast was difficult. The most important part was generating the short hand codes to be able to properly track the subjects. During our exercise, our code evolved to better track the game. An example of that was originally we only had ...
