New phone means new things…<\/strong><\/p>\n

My Android phone was ridiculously problematic. \u00a0The battery life wasn’t reliable\u00a0and the reception spotty. \u00a0I finally conceded and replaced it with a iPhone 4s. \u00a0I have a 5s already and use a case on my bike to house it while travelling. \u00a0The new phone is a bit shorter than the 5s, so I thought I’d check with the case manufacturer for a 4s case.<\/p>\n

The manufacturer is Tigra Sports<\/a> and they offer a variety of products. \u00a0They have the 4s case, but the mounting hardware is different than the 5s…bummer. \u00a0But I did notice they have a heart rate monitor<\/a> that is non proprietary. \u00a0It uses BLE, also known as Bluetooth Low Energy<\/a> technology. \u00a0The price of the monitor is reasonable, and the fact it’s non proprietary gives it potential for use in projects.<\/p>\n

We have a board for that…<\/strong><\/p>\n

There is a board made by Adafruit that allows\u00a0BLE integration<\/a> with microcontroller projects. \u00a0Linking devices that use BLE is simpler, based on the demo provided. \u00a0It stands to reason that this board would be the mediator between the Tigra heart rate monitor and the Arduino. \u00a0I assume that a second board would be required to communicate with a smart phone with BLE support. \u00a0I’m getting the impression that BLE is a point to point comm link, not a star mesh link.<\/p>\n

Displaying sensor readings in real time…<\/strong><\/p>\n

This would be particularly useful with the sensor helmet. \u00a0Having the ability to view\u00a0telemetry while riding could be insightful. \u00a0This will require the development of an app to display the values that are easy to understand. \u00a0The data storage chip is well suited for a global view, such as heat maps. \u00a0The live display can help identify conditions that may not be available afterward. \u00a0One example would be a spike in smoke detected on the sensor, but there is no\u00a0additional information about the source. \u00a0Live readings would allow the rider to investigate upon noticing the spike.<\/p>\n

Multiple points of detection…<\/strong><\/p>\n

Having the chest sensor also allows me to validate the readings from the helmet heart rate sensor. \u00a0I’m also curious about multiple heart rate detection points to provide more data besides heart rate, such as blood pressure. \u00a0I will need the services of someone qualified in medicine to develop something this advanced. \u00a0However, the sensor technology is becoming smaller and more available. \u00a0These factors make it possible for this level of precision.<\/p>\n","protected":false},"excerpt":{"rendered":"
