Description

product description:

CO, SO2, H2S, PH3, HCN, NH3 sensor signal processing and conditioning boards are provided by a team with long-term experience in related development to provide comprehensive after-sales technical services, and can also purchase sensor probes to help customers quickly apply!

Port introduction:

  1. Power supply: +3.3V~+5V;
  2. Signal output: linear analog signal (the output range needs to be adjusted according to the probe model, signal amount, and range of the signal board parameters, and due to the difference of the probe, a single device needs to use calibration gas and acquisition application software to correct the linear slope);
  3. Reference voltage: +2.5V, accuracy 1%, externally output by the signal board, which can be used to collect the external Vref voltage of the microcontroller to improve the sampling accuracy;
  4. Power-on control: effective at high level (>2V), mainly used for range overload protection, and interval collection applications that need to save energy (such as battery power supply). After power-on again, stabilization time is required (5~10 Minutes) before collecting data!
  5. Sensor probe: Suitable for three-electrode sensors of other manufacturers such as 4CM, 4S, 4HS+, etc. Read the introduction of each probe in the shop in detail, and when the probe is first connected, it takes 5-10 minutes to stabilize!

other:

  1. Provide supporting probe service
  2. Support customized services (analog output, digital output, wireless acquisition, touch screen acquisition, host computer monitoring, etc.)
  3. Schematic diagrams, PCB, source code services are not provided for direct-sale products in stores;
