Abstract
With the development of Internet of Things, in addition to the basic counting function, the counter also needs to integrate more functions to meet the application requirements, such as display, communication, charging functions and other functions. Therefore, it is very necessary to design a new electronic counter which has an ability to communicate with outside, display counting information and energy supplement. In this paper, we design a new electronic counter based on the pulse counting theory, information communication theory and flash memory technology. First of all, we will count the pulse signal through the signal input circuit and the signal processing circuit into the control circuit, which can identify the digital pulse signal. Secondly, the control circuit count the number of digital pulse signal, the count number will be real-time displayed on the digital tube. Meanwhile, the counter communicates with the Bluetooth device (smartphone, pad, etc.) via the Bluetooth module. And users can use the Bluetooth device to configure the counter's operating parameters, clear or pre-count values, view the counter operating conditions and historical data.
Highlights
With the development of Internet of Things (IoT), sensors are deployed in a variety of applications, to sense the building infrastructure, environmental information and control operation procedures automatically [1, 2]

Summary
With the development of Internet of Things (IoT), sensors are deployed in a variety of applications, to sense the building infrastructure, environmental information and control operation procedures automatically [1, 2]. In the new electronic counter, we employ various of functional models to improve the counter function, such as the control circuit, power supply circuit, digital tube display circuit, illumination sensor, real-time clock circuit, flash memory, signal input circuit, signal processing circuit, keypad, indicator light, Bluetooth module and antenna as shown in figure 1. The control circuit is connected with most of models, such as the power supply circuit, the digital tube display circuit, the illumination sensor, the real-time clock circuit, the flash memory, the signal processing circuit, the keypad, the indicator light and the Bluetooth module, and the control circuit is used for controlling the work of each peripheral device [5]. The power supply circuit is connected with the control circuit, the digital display circuit, the illumination sensor, the real-time clock circuit, the flash memory, the signal processing circuit and the Bluetooth module. The antenna is connected to the antenna interface of the Bluetooth module and the antenna is used to radiate and receive wireless signals
