Polar Heart Rate Sensor Wireless Transmitter:

The Non-Coded Heart Rate Transmitter monitors and then wirelessly transmits your heart rate data from the chest strap to a compatible receiver.  This allows the wearer to monitor their heart rate and related bio-metric statistics.

Key Features:

• Heart rate sensor wirelessly transmits heart rate data without the need for conductive gel
• Water-resistant up to 30 meters for use in extreme environments 
• Battery to last up to 2,500 hours of continuous usage
• Adjustable elastic strap for comfortable yet secure sensing
• Removable and machine washable textile strap keeps your sensor bacteria-free

Details:

• Water resistant up to 30 meters
• ECG accuracy
• Up to 2,500 hours of usage
• Non-user replacable battery
• Adjustable medium size elastic chest strap included (25-54 inches)
• Machine washable and anti-bacterial

Heart Rate wireless Receiver:

The Heart Rate Receiver is a receiver capable of wirelessly receiving coded heart beat transmissions from the Heart Rate Sensor.  With its standard servo interface pinout (Vss, Vdd, Sig), interfacing with this receiver is very simple - upon receipt of a heart beat signal, a 15 ms pulse is sent on the signal pin.  This receiver also features a longer reception distance, giving you added flexibility in your application.

Key Features:

• Receives coded or non-coded signals from Heart Rate Transmitters
• 80 cm reception distance gives you greater range from the transmitting heart rate sensor 
• Long 15 ms pulse on received heart beat gives your processor ample time to sample a pulse 
• Interface connector is not pre-installed to give you prototyping flexibility 
• Standard servo connector compliant for easy interfacing
• Any microcontroller (not included) like Basic Stamp, Arduino etc may be used to process data.

Details:

• 3 pin .1" pitch header (servo compatible)
• 80 cm reception range
• Dimensions: .75 in x 1 in (19 cm x 25.4 cm)
• 15 ms TTL level high (Vdd) pulse on received heart beat
• 3v - 5.5v supply voltage range
• 200 uA current consumption @ 5v
• Operating temp range: +40 to + 122°F (+5 to +50 °C)
