Digital power amplifier board with volume potentiometer, two-channel stereo noiseless

Two-channel stereo, 5V power supply can output 5W+5W power, can directly drive 4Ω, 8Ω small speakers, with high output power, sufficient energy, good sound quality, with left and right channel volume adjustment.

The unique Class D digital power board without LC filter can be directly powered by the computer's USB.

Double panel wiring, properly solve the ground potential balance and crosstalk between channels caused by wiring

Ultra-micro design, can be easily placed in the small internal space of various digital products, with super high magnification efficiency.

The rated working voltage is 2.5-5V, and the ultimate working voltage is 5.5V.

Water & heat meter
Measurement and registration for the purpose of commercial and technological accounting of the values of the consumed (supplied) amount of heat (thermal energy), heat carrier and other parameters of heat supply and hot water supply systems, as well as for the organization of information data collection networks.

Connection of up to 4 flow meters in one heating system;

Separate accumulation of data on the heating system and hot water supply (DHW) within one heating system;

Archiving of all integral meters with a cumulative total;

Simplified setup;

Additional channels for pump control according to a schedule, according to sensor signals (flow, temperature, pressure), leakage prevention or alarm management;

Saving data to a standard USB-flash drive;

The time for receiving a full archive via USB connector is up to 40 seconds;

High operational reliability;

Calibration interval - 4 years;

RS-232 / RS-485 (ModBus), USB, Ethernet, 3G interfaces;

Ease of installation - setting up the heat meter at the installation site;

No additional hydraulic resistance;

Wide range and stability of flow measurement;

High accuracy - class 1 and 2;

The heat meter provides for automatic switching of the "Open" system operation mode during repair work in the summer period (automatic switching between the "Main", "Summer1" and "Summer2" modes; only for versions with induction channels).

Temperature sensing
Products are widely used in warehouses, transportation, medicine, electric power, agriculture, households and other occasions. It can realize 24 hours unmanned monitoring and automatic data collection according to needs, and multiple permissions can be assigned to relevant personnel at the same time. If the temperature and humidity are abnormal, it can respond in time to reduce the loss to a low limit.

The communication method of the collector is GPRS (no distance limit) or WiFi. The necessary conditions for realizing GPRS data communication include: (a. Have a fixed IP or fixed domain name b. Have a SIM data card (mobile phone card is also available))

The collector has a built-in 4000MA, 3.7V high-quality high-capacity rechargeable lithium battery (charging voltage 5V), and the power consumption is less than 7uA in the standby state. Measured data: XM200G sends data once per minute when fully charged and can send 13,000 times; XM200W sends data once every minute when fully charged and can send 40,000 times

Users can view the temperature and humidity data uploaded to the cloud center: use a computer/tablet/mobile phone to log in to the Web site to view, and use the mobile phone APP to view

Temperature measurement range, resolution and accuracy: -20℃～ +60℃, 0.1℃, ±0.5℃

Humidity measurement range, resolution and accuracy: 0% ～ 100 (RH) relative humidity, 0.1%RH, ±3%RH
