ESP32 Sensor Node with built-in battery and solar charging
Designed standalone installations in environments where grid power is not available.
Inbuilt LiPo battery can power the device and external sensors for hours, and there are provisions to connect a 6V Solar panel to enable charging.
The device has WiFi connectivity as standard and GSM/LTE , NB-IoT, LoRa can be ordered as options. Which makes it the perfect standalone sensor node, which can also be a gateway
