HS Huaxin, HS Datasheet

A bit of theory Just a little bit. This is the digital equivalent to the Amplitude Modulation AM used in long distance radio broadcast. Going one step further I was wondering datasheey the simple Mhz transmitter for my Arduino would be capable of drowning out the professionally made magnet contacts.

The information is encoded as an increase or decrease in the amplitude of a carrier wave of in this case Anyway, you know what they say: And I also could send an identical signal via RC switch, it detected a PulseLength of microseconds.

This datasheett supersedes and replaces all information previously supplied. To sum it up: However, HuaXin Micro-electronics assumes no. HuaXin Micro-electronics products are not authorized for use as critical components in life support devices or systems without express written approval of HuaXin Micro-electronics.

HuaXin Micro-electronics assumes no responsibility for the mismatch occurred. However, in order to have identical signals in my poor-osci I had to use microseconds also for RC switch.

This post is the second part of a previous one where I explain the daatasheet I used to analyse the signals from the wall outlets, check it out here: If you are lucky you might just need and Arduino and one of the two libraries I mention in the post: The preamble is sent back-to-back with the preceding bitstream.

Trick the alarm into thinking a window opened, after the alarm gets armed.

The first set of 5 are the channel the he1527 you configure in the dip switch of the remotes and the outlets. Take a rest from the project and come back in a day or two and you might find yourself the answer….

Avidsen remote These remotes use the PT parallel to serial encoder datasheet. Note that you can speak these patterns in different ways: Let me show you! No license is granted by implication or otherwise under any patent or patent rights of HuaXin Micro-electronics.

The next image shows the pattern for these 3 states:. The four buttons on the remote are tied 1: But this number is just a convenience and we are moving away from the actual signal representation.

The bitstreams generated by one of the contacts are as follows: Only the four rightmost bits change. The actual parts dtaasheet may not completely agree with the description. Leave a Reply all comments are moderated, be patient Cancel reply.

However, HuaXin Micro-electronics assumes no responsibility for the consequences of use of such information nor for any infringement of patents or other rights of third parties which may result from its use.

There is no OTP going on here! Just one more thing, there are a bunch of things that will vary from device to device: Any ideas why the problem could be? For starters, I assumed that each sensor would use the same HS with a different set of data sent for various states. I had to go a little further and used a BusPirate and OLS Logic Analyser to get a graph of the pulses and understand what was going on there was a slight modification on the encoding that prevented the libraries to decode the signal.

Information furnished is believed to be accurate and reliable. The information itself is sent at lower frequencies some tens of KHz.

That way the home owner does not get alerted about leaving something open when leaving the home.
