As more and more progress in economic, the environmental pollution is getting worse. People need to detect the current of pollution. It is necessary to detect through instruments, but traditional analytical instruments are bulky, inconvenient and more of the power. Traditional analytical instruments can’t real-time detect pollute. People need a portable instrument that is easy to carry and can immediately detect the state of environmental pollution.
Portable sensors system currently on the market is usually made only for a single purpose and it can not replace the sensor. The ESPMS system (energy-saving portable multi-channel sensor system s) can use several different types of sensors, and sensors can be replaced.The ESPMS system can update the firmware from computer. When the ESPMS system was updated, the ESPMS system can accurately measure changes in the amount of analyte present. The results will be displayed on the LCD and stored in the system. The ESPMS system can be used as a sensor array to detect the pollution.
The traditional portable sensors systems were powered by the battery or rechargeable battery. It can’t work when the battery was no power. The ESPMS system uses "green energy" solar cells appear to resolve this part of the trouble, because solar energy can provide power to the ESPMS system and battery to extend the use of time. Power management device control the power on the ESPMS system. When the power management device detects a USB power or power supply,it will store power in battery. The ESPMS system can set the standby time. When the system was outside the standby time and the user does not continue to use the system, the ESPMS system will enter the sleep state, power off all devices around, and then save energy.
