Street light control using WiSense WSN1101L
We recently built a prototype to control a mains powered street light in our community. This node has a WSN1101L node interfaced to a relay. The relay is controlled (through a driver IC) by a GPIO pin on the WSN1101L’s micro-controller. Power supply is through an 230 V AC to 12 V DC module. All the electronics is housed in a weather proof enclosure.
The node has been working properly for a week now. The node has been configured to operate as a full featured device (FFD) which simply means that it is involved in mesh routing.
The WSN1101L operates in the license free 865-867 MHz license free band in India.
Connected street lights can save power and ease fault detection and maintenance. We are going to build another prototype which will monitor current consumption and light output.
I have included some pics below.
