I was concerned when the packaging looked like it had been wet. The boards were in plastic, but the receiver board had a white crust on it. I gave it a try anyway…no joy. It didn’t work

Had to do a bit of digging to get the correct software. Google for 'arduino serial communication'. This is the only transmitter/receiver pair that I have found, that works.

I am controlling this with an Arduino using the Virtual Wire library. There are many such receiver modules like this out there for receiving on 433 or 315 MHz. Some work great. Some do not. This one works well. I could get a solid 100 foot reception range from a FS1000A transmitter. People say they can get hundreds of yards out of these 433 modules, but in practice, unless you have a large dipole antenna, a 100 feet for accurate reliable message passing is about it, especially if you need to go through some walls or have other interference in the area. The antenna is importanrt. Don't use the coily little wire that comes with it. That will limit you to about 10-15 feet of reception. The whole subject of antenna design for these things is a complex subject I can't go into here. Suffice it to say, I found 3 different brands of 433 superhet receivers that work well with Virtual Wire on an Arduino, and this is one of them. I'd buy them again.

These are the "better" ones. At least for Arduino / ESPHome projects. Avoid the cheaper, more common (to find) ones available. Those generally don't even come with an antenna. You get 1–2-inch range. Even with an antenna the other type have like 1 foot range. Look for "Superheterodyne" or get these.I used these to create a "Harmony Remote" replacement on ESPHome with Home Assistant. A generic RF remote triggers Home Assistant to control media devices via a Broadelink RM4 Pro.

These worked fine with the Arduino RCSwitch library. Mine had the same markings as another reviewer that said they were 315mhz, but I can confirm that mine are 433Mhz even though the crystals have different numbers than the picture in the product listing. They have a slightly longer range and perform a little better than the cheaper 433Mhz sender and receiver units you see. Solid performance at 150' and worked to around 200' (no obstructions) with the supplied antennas. Max range was 200' but a little spotty beyond 150'. Worked from everywhere in my house, going through 4 walls and a floor.

I tried it for a couple different sensors, but it does not work. Little documentation

Compared to the other less expensive units that come in a lot, this RX/TX combo works beautifully. Use it with the RCSwitch library and you're in business! The antenna and the crystal make a WORLD of difference. Wasted an entire day trying to get the other units to work with custom antennas of various sizes with no success. The 3.3V and size make this a perfect battery project. Use this in conjunction with a PIR + Doppler radar and you will have the perfect human detector sensor.

The chip that I got was NOT 433.92MHz (which is what is shown in the description). It is only 433MHz.The project I was using it for was not receiving the 433.92MHz signals but was receiving a 433MHz signal I had.The chip did work (was not dead on arrival) so I gave it 2 stars for that. Unfortunately I can't use it for what I need.
