I'm the type that wants to understand how a system works rather than blindly copy existing code or a library that I can't understand. So that others may benefit here's some gereric code -. Please, could some people who have sucessfully got one of these to work read the comments and tell me if everything is correctly documented. Additionally - many of the clone modules use counterfeit chips, sometimes with slightly different names and different pin outs, but they all respond to the Hx comms commands correctly. This would seem to support the claim that the chip can be run from as little as 2. Can you please post a circuit diagram? Can you please post a image s of your project?

According to the datasheet it can be powered by a 3. The datasheet indicates this device can be run from a 3. The datasheet provides an example circuit demonstrating how this ADC can be used to measure weight from a scale sensor:. To get a better idea of how this sensor works it would be helpful to locate its product number. I had a hunch it was beneath the part so I desoldered it, and indeed I found part identification information. The pressure sensor is labeled as a PSGS but unfortunately I struggled to find a quality datasheet for it. I did find some now-deleted images from an AliExpress listing showing the differences between the base model and the R and S variants. This seems to be a fairly standard differential pressure sensor design using a pair of voltage dividers where the pressure is a function of the difference in voltage at the two mid-points a Wheatstone bridge. I used a multimeter to determine the resistor network inside this pressure sensor. Interestingly I found that pin 4 was not connected, which is opposite of many other designs I find online where pin 5 is not connected. It is critically important to get this right if your goal is to design a PCB around this component. I also question if people are getting confused and reporting the mirror image pinout because they mistake the vent hole for the registration marker. Either way, I made the following diagram which I found helpful:. Update : I received an email from somebody offering additional information about this component:. The PSG reports positive and negative pressures and can easily have its range shifted to almost double in one direction with almost none in the other.

Thanks a lot.

The HXB is a precision bit analog-to-digital converter ADC designed for weigh scales and industrial control applications. To simplify the digital interface initialization, the device incorporates on-chip power-on-reset circuitry. Additionally, the HX includes an on-chip oscillator that provides the necessary system clock without the need for external components. The internal registers of the device do not require any programming, as all controls are managed through the available pins. Even though it is designed for weighing scale applications, you can find them in many other sensing circuitries such as pressure sensor and more. The following image shows the typical application circuit for the HXB. In HXB , the on-chip oscillator serves as the clock source. The nominal output data rate for this version is either 10 or 40 samples per second.

A load cell converts a force into an electrical signal that can be measured. The electrical signal changes proportionally to the force applied. There are different types of load cells: strain gauges, pneumatic, and hydraulic.

The datasheet indicates gain is fixed at and cannot be changed in software. You switched accounts on another tab or window. The microcontroller must allow time for this signal to become valid before reading the Data bit in; typically 1us on wires up to 5m long. AlbiBone what you say is correct, but there are two versions of the HX Tom, I have no physical devices, covid delays they say This library easily works with the HX for basic functionality. Some clone chips wake up in the mode they were in when put to sleep; check your datasheets! Both Control and Data are high during sleep. One ends on 'a', the other on 'b'. The following is what I think it actually means -. TomGeorge May 26, , am 2.

According to the datasheet it can be powered by a 3.

You switched accounts on another tab or window. Both Control and Data are low when the conversion is completed and valid data is available. If you send 26 pulses you get: -either the reading of the thermocouple if you have the 'a' version at a sample rate of 40 hz -or the DVDD-AVDD if you have the 'b' version at a sample rate of 40 hz Hope that makes things more clear See this datasheet for further reference: Datasheet HX A:B. However because on the HX the setup and config of the chip is not done in hardware but in software, the library would have to be updated. What model Arduino are you using? You signed out in another tab or window. Thanks a lot All reactions. The set gain function worked as expected Thanks a lot. Both Control and Data are high during sleep. You have done all your research, now write code for each section, to prove they work before putting it all together.
