Itokii wireless temperature sensors use a thermistor to accurately measure temperatures. These sensors are perfect for monitoring ambient temperatures around the sensors physical location. User customization allows you to set the frequency of readings and the ability to set thresholds for alerts via SMS text and/or email.
NIST certified product is available on leaded temperature sensors (select a lead length in order to see available certifications).
If ordering NIST certified temperature sensors orders may take up to 6 weeks to ship.
- Accurate to +/- 1°C (1.8°F).
- Available with an external temperature probe.
* Actual range may vary depending on environment.
** Battery life is affected by reporting frequency (heartbeat), sensor type, Wi-Fi security type, distance from Wi-Fi router and other variables.
In order to program the sensor to connect to your wif-fi network, you will need a Wi-Fi programming cable and the free IoWi setup utility. The IoWi setup utility is currently available for Windows® PC's only. Mac and Linux are not currently supported!
