Specification parameters of hardware parts
1.Humidity and temperature signal
Temperature and humidity signal using single line digital temperature and humidity sensors. The main parameters are as follows:
1) humidity measurement range: 20%-95%, measurement error: ±5%
2) temperature measurement range: 0-50 C, measurement error: ±2ºC
3) working voltage:5V
2. Dry contact input signal
Isolated input, dry contact input signal is isolated to internal circuit
3. Electric energy signal
Electric energy signal can provide three kinds of power signal interface: RS485, infrared, camera. For an electric energy with RS485 interface or infrared interface, it read signals through the RS485 or infrared interface. For vintage electric energy without external interface, signals can be read by the camera.
4. Dry contact output control signal
Isolated output, dry contact output control signal is isolated to internal circuit
5. 3G, Wifi interface
Automatic selection of 3G and Wifi interface. When there is Wifi, it use Wifi to transmit signal ,  when no Wifi, it automatically switch to the 3G network (3G interface should has access to SIM
Card).
6. Bluetooth interface
Bluetooth is version 4, can be connected with Android, Apple mobile phones and PC machine communication. (patrol is the use of Bluetooth interface)
7. Backup battery
Backup battery using 1000mAh 3.7V lithium battery, when in power outages, backup battery's working endurance is 2 hours (optional with a higher capacity)
Functions of Server software
1. Data acquisition controller timing (tentatively 10 seconds) to save the data sent up
2. End users (administrators, staff) manage account password
3. The administrator can query online data's statistical situation on DAC in the background, and also can choose to view a certain DAC's related data
4. Administrator can print various reports in the background
5. Receives the command of the administrator, and sends the command to Data Acquisition Controller, such as setting the alarm threshold, etc.
6. In response to the data request of terminal user (administrator, staff), if the corresponding data of the server has expired, it will send the data request to Data Acquisition Controller, and will  respond to terminal user (administrator, staff) with updated data,(Electric energy in picture format can identify the value better)
7. Record the operation log of end user
8. According to the error state of the controller, send a notification to the administrator and the first responsible person, if the first responsible person did not respond, will be in the form of text messages to inform the first responsible person and notice 6 / 6 to second responsible person, if the second responsible person does not respond, then in text messages to inform the second responsible person. All notifications are made to the log.
9. Record patrol maintenance log
Functions of mobile app(Android and Apple)
1. Log in and connect server
2. Check the online list on Data Acquisition Controller, and can choose to view a certain Data Acquisition Controller's related data
3. Administrator can modify a variety of alarm thresholds
4. Can control a certain data acquisition controller output dry contacts
5. According to abnormal data to collect information of the data acquisition controller, highlight the situation of the data acquisition controller
6.Patrol (open the Bluetooth connection via Bluetooth data acquisition controller)
