Update: 2017 April 19 - We'll be shipping V3 version of BLEThrowie (photos come soon). Update: 2015 December 31 - iOS app now displays temperature and humidity as a graph. Update: 2015 December 16 - we are offering a plastic case for BLEThrowie - 3 USD per case. Customers, who already bought Throwie V2 can get it too - just let us know how many cases you want.
Update: 2015 October 15 - from now on we will be using Temp/Rh sensor with factory installed cover to protect sensor from dust.
BLEThrowie V2 features Over-the-Air software updates, a one-week temperature and humidity log. Also - latest Temp and Rh readings are retrieved without connecting to sensor, it's is passed in advertisement packets, so on-screen updates are faster. We have made the sensor smaller, temp sensor is placed on a milled PCB section to minimize board temperature influence, I2C communications take less time (hence less energy and gives better battery life). Voltage regulator was added to squeeze more juice from the battery.
Meet the BLEThrowie – an inexpensive yet precise Bluetooth Low Energy(BLE) data logger. It stores temperature and humidity data. Sensor data is provided by a digital temperature and humidity sensor. Ever wanted to know how hot it gets in your house after you turn off the AC, or how much time it takes for your gas stove to reach the desired temperature, is there a moisture build-up in your house after you installed that smart thermostat from Google? Those are simple measurements that require data logging and an easy way of reading those measurements. We know that professional data loggers have been around for years, but they were expensive and cumbersome to use. Hobby-level analog sensors were not accurate and did not have application support. Changing batteries sucks, so we made BLEThrowie to be power savvy. Luckily this was possible with CC2541 System on Chip (SoC) from Texas instruments and temperature/humidity sensor from Silicon Labs.
What if you could have a data logger that would log temperature, humidity and light level with precision and would be accessible from your smartphone? We at Singleton Labs have been developing measurement data visualization software since 2001, so we created apps for iOS and Android that display BLEThrowie data nicely. Take a look at BLEThrowie App video to see how easy it is to use data logger from our applications. Applications are free of charge.
iPhone application can be downloaded from App Store at: BLEThrowie@iOS
