General information

---

The EnvLogger system comprises a miniaturised, rugged temperature logger and a companion smartphone app. Both were designed with an emphasis on reliability and ease of use. The logger communicates with a smartphone using wireless Near Field Communication technology. To communicate, it is only necessary to “tap” the loggers with the smartphone.

EnvLoggers are available in two hardware formats, T2.4 and T7.3. 

T7.3 is vastly superior to T2.4 regarding memory, battery life and clock drift, but is slightly larger and more expensive.

Both hardware versions (T2.4 and T7.3) can be supplied in a virtually endless variety of shapes and colours. These can be grouped into three main categories: 

1. naked electronics; 
2. encapsulated in hard acrylic, and 
3. as biomimetic loggers (resembling real animals).

The hard acrylic disks are completely watertight and can be deployed in dusty, subaquatic, UV-rich, or moderately corrosive environments. They are also quite resistant to mechanical stress, and because communication is wireless, they can be embedded in hard materials such as rocks (or made into biomimetic loggers). Look below for a comparative table between the various readily available formats. Custom-made formats are available upon request.

EnvLoggers communicate via a dedicated app, freely available for Android and iOS smartphones. On your smartphone, go to the Android's PlayStore or to the iOS App Store and download the app EnvLogger Viewer. If your smartphone is incompatible, the app will not appear in the store. Keep the app updated to benefit from new features.

With the dedicated smartphone app, logger servicing is rapid and easy. This, in turn, facilitates the establishment and maintenance of large networks of loggers serviced by multiple scientists and/or citizens.
