Product / Service Details

Description

All the accumulated data can be sent to a LoRaWAN® gateway in order for it to be forwarded to the Cloud.

Because of its design, tWisNode Sense Home can achieve a very low power consumption rate, which with the included non-rechargeable battery allows for 2+ years of operation.

The firmware has built-in functionality that allows the user to adjust the sampling interval of the sensors and the transmission cycle.

Last but not least, WisNode Sense Home adopts a highly integrated design, fitting the electronics and battery within 90mm x 85mm x 34mm casing.

Note :
1. The included battery is non-rechargeable. In case you need to plug in the Micro USB port for the purpose of configuring the node, the battery should stay plugged.

2. The pin distance of the battery connector is 2.0mm. When choosing a battery, attention should be paid to the consistency of positive and negative poles. Reverse connections or short circuits may damage the device and may cause overheating and combustion of the battery. Therefore, when replacing the battery, it is necessary to strictly confirm whether the positive and negative poles of the connector are correct.
