![]() Moreover it can also be used to control electronic appliances in home or in office, making home or office security projects, door locks etc. For example if you require a continuous temperature monitoring inside or your house or outside, temperature monitoring of machines running in factories. However if you want two way communication then you can also use other modules like HC12, NRF24L01 etc.įS1000A 433MHZ RF transmitter & XY-MK-5V receiver module can be used in any project where there is a requirement to send data through air under short distances. But it can be used for verity of purposes where there is not any requirement of two way communication for example wireless temperature sensor, switching home or office appliances, and transmitting data. The module only transmits one way because in this pair one is a RF transmitter and other is RF receiver. The max stable data transfer rate is 10kb per second. These modules are available in three different frequencies which are 433MHz, 315MHz & 330MHz therefore you can buy according to your frequency requirements. ![]() The transmitter part can be operated from 3V to 12V and the maximum output can be achieved on 12V with 17cm antenna at both sides. This module is used by vast majority of electronics DIYers due to its low cost and easy implementation. XY-MK-5V (Receiver Part) Features & Technical Specifications:įS1000A (433 MHz/315 MHz/330 MHz RF Transmitter) & XY-MK-5V (433MHz/315MHz/330MHz RF Receiver) is a pair of low cost radio frequency module for one way wireless communication for arduino, raspberry pi and other platforms. Data Transfer Rate: Transmitting Range: 20 to 100 meters through walls & 500 meters max in open area.Transmitting Frequency: 433.92MHz, 315MHz, 330MHz.If you are new to nRF24s it may be better to start with a pair of low power modules with the pcb antenna.FS1000A (Transmitter Part) Features & Technical Specifications: ![]() However someone on the Forum has had them working without that separation - I don't have any personal experience with them. If you are using the high-power nRF24s (with the external antenna) it may help to have a distance of about 3 metres between the two nRF24s so that the signal does not overwhelm the receiver. At least for testing try powering the nRF24 with a pair of AA alkaline cells (3v) with the battery GND connected to the Arduino GND. The high-power nRF24s (with the external antenna) will definitely need an external power supply. This seems to be a particular problem with the nano. Nothing will work if the connection test fails.Ī common problem with nRF24 modules is insufficient 3.3v current from the Arduino 3.3v pin. If the first example does not work be sure to try the connection test for both of your Arduinos. There is also a connection test program to check that the Arduino can talk to the nRF24 it is connected to. Start by getting the first example to work If you get stuck it will be easier to help with code that I am familiar with. The examples are as simple as I could make them and they have worked for other Forum members. Wireless problems can be very difficult to debug so get the wireless part working on its own before you start adding any other features. Have a look at this Simple nRF24L01+ Tutorial. When I connect a different module to the receiver side, it posts nothing. Same thing when I don’t connect a module at all. ![]() The receiver keeps posting received positive. Read payload, and check if it finished Setup the channel to work within, number 100īool success = radio.write(&info, sizeof(boolean)) Address to devices comunicate each other (same in both) Instantiate RF24 class with CE and CSN values One of the codes I tried is this one: //transmitter I have tried different codes that seem to work with other people.I have tried different nrf24l01 module combinations.I have used a different power source than the Arduino 3.3v pin.I have added a 100uf capacitor between 3.3v and ground.I have banned long jumper wires and soldered the circuit on perfboard (checked for continuity).I am aware that many other people have the same problem and many solutions have been found.
