Light Pen

A wireless control system for pointolite on the light pen based on TMS320DM642 and CC2530 is introduced in this paper, in order to solve the problem that only pointolite's switch values could be controlled on the light pen in light-pen CMMs, but not lightening time values and brightness values. Through wireless networks of Zigbee, not only pointolite could be switched on or off separately, but also lightening time values and brightness values could be changed by TMS320DM642. Protocols of wired and wireless communication, multipoint answer and error reporting are also given, to improve anti-jamming capability of the system. The experimental result demonstrates that the control success rate could reach 96%, as the wireless modules of TMS320DM642 and the light pen within 8m. So the developed system has high anti-interference capability and could meet expected requirements.

In this paper, we report a smart street lighting control system using the ESP8266 which is a low-cost Wi-Fi chip with full TCP/IP stack and microcontroller capability. Our system is equipped with a web server developed in HTML code. Hence, our smart street lighting system can be controlled wirelessly to turn ON or turn OFF, and it can be monitored its environmental condition (i.e., temperature and humidity around the system). All sensors used in this system are pure digitally-outputted sensor: DHT11 to monitor the ambient temperature and humidity and BH1750 to adjust the street light intensity automatically. The dimming technique was applied in the control system by using Pulse Width Modulation (PWM). The system was divided into two main parts: Gateway and Node in which these two parts employ the ESP8266. The Gateway as a coordinator will send a message to the node as an end device (in this work, the streetlight act as a Node). Later, the node will send the ACK to the Gateway. As results, each node can send a message to other nodes.
