LPWAN wireless protocols like LoRaWAN, Sigfox, and NB-IoT enable long-range transfers of small amounts of data at very low power for a battery life of up to 10 years. But there’s still a need to replace the battery from time to time increasing maintenance costs.
HiSilicon and Nowi have partnered to design and launch the Energy Autonomous NB-IoT V2 Platform, a sensor hub that can transmit via NB-IoT without the need to change or recharge batteries manually through its energy harvesting capabilities.
Energy Autonomous NB-IoT V2 Platform key features and specifications:
- LPWAN module – Quectel BC95 module based on HiSilicon Hi2115 NB-IoT chip
- Max transmissions per day
- Up to 3 transmissions per day in indoor conditions
- Up to 6 transmissions per day in outdoor conditions
- Power Management
- Nowi NH2 (MH2D02564) energy harvesting power management IC
- Can operate with a range of photovoltaic (multiple) cells
- Dimensions – 5.5 x 3.5cm
The second generation Energy Autonomous NB-IoT board is said to have significantly decreased PCB size and bill of materials. You can register your interest in the reference design and the schematics and the company will start providing samples in August 2020 to selected organizations.
Nowi NH2 mass production is slated to start in Q4 2020. A few more details may be found in the press release.
