Receivers
The receiver comes in different shapes, prices, and qualities. It can differ greatly in quality. So the first step is buying the right receiver. Below, I’ve created a list of all receivers I’ve tested in order of achievement.
Note: it is recommended to install a low-pass filter
The following receivers have been tested:
433.92 MHz
| # | Tester | Name | From | Price | Experience |
|---|---|---|---|---|---|
| 1 | CurlyMo | Shenzhen RXB6 | Ebay | $ 10 (kit) | + Tested to work in at least 30m range (with simple antenna) @5V It already has a PCB antenna - Generates a lot of noise w/o a LPF + Works perfectly with a LPF |
| 2 | CurlyMo | Shenzhen RXB14 | Ebay | $ 4 | + The same as the previous receiver + Cheap - No PCB antenna (External antenna required) |
| 3 | CurlyMo | Aurel RX-4M50RR30SF | Conrad | $ 20 | + Tested to work in at least 30m range (w/o antenna) @5V + Generates less noise due to some filtering - Still needs a LPF + Shielded - Massively expensive |
| 4 | CurlyMo | Standard | iPrototype | $ 7 | - Works only within a 4m range @5V and is thereby unusable + Has low noise output - Doesn't work well with the a LPF because it has an onboard amplifier - Adding a Schmitt-Trigger makes the noise almost absent + Expensive |
| 5 | CurlyMo | DX H5V4H | DealExtreme | $3,5 | - Works only within a 4m range @5V and is thereby unusable - Generates a lot of noise - Untested with a LPF |
| 6 | CurlyMo | Standard | Ebay / DealExtreme | $2 (kit) | - Works only within a 4m range @5V and is thereby unusable - Generates a lot of noise - Untested with a LPF |
| 7 | Marcel | Standard | Conrad | $35 (kit) | Tested to work within 5-10m (without a LPF) @5V |
| 8 | Accountabc | Qiachip WL102-341 | Aliexpress | $1 (kit) | + Tested to work 15-20m/10m through concrete floors with 17.3 cm wire antenna (with Arduino Nano receiver) @5V + Cheap |
Some Comments
The Aurel receiver has been promoted as being the best receiver out there. My experience is otherwise. You can buy 3 Ebay senders / receivers kits + LPF for the same price and they work evenly well as the Aurel receiver. It still needs some sort of post filtering to be perfect so the cost of a filter adds to the standard price of the receiver. However, the filtering was not yet tested.
The following devices are not working as expected
| # | Tester | Name | From | Price | Problems |
|---|---|---|---|---|---|
| 1 | Diman87 | Aurel RX-4M50FM60SF | Conrad | 34 € | - Generating much noise without BPF - not working with a BPF - Corresponding topic: Aurel 433,92 MHz -111 dBm |
