The **AK-AV100-R** is a specific electronic component, primarily recognized as a **high-sensitivity wireless receiver module**. It is commonly used in remote control systems, security alarms, and wireless data transmission. --- ## 1. Technical Specifications The following table outlines the core electronic parameters of the AK-AV100-R: | Parameter | Specification | | :--- | :--- | | **Operating Voltage** | DC 3V to 5.5V | | **Operating Current** | ≤ 5mA (at 5.0V) | | **Operating Frequency** | 315MHz or 433.92MHz (Standard) | | **Modulation Method** | ASK / OOK (Amplitude Shift Keying) | | **Sensitivity** | -108 dBm | | **Transfer Rate** | Up to 10kbps | | **Output Level** | TTL / CMOS compatible | --- ## 2. Pin Configuration The module typically features a 4-pin or 5-pin layout, making it easy to integrate with microcontrollers like Arduino or PIC. 1. **ANT:** Antenna connection point (usually a 17cm wire for 433MHz). 2. **VCC:** Positive power supply (3V-5V). 3. **DATA:** Digital data output (connected to MCU input). 4. **GND:** Ground. --- ## 3. Core Electronic Features ### Superheterodyne Architecture Unlike cheaper "Super-regenerative" modules, the AK-AV100-R uses a **superheterodyne** design. This provides: * **High Stability:** It is less affected by environmental temperature changes. * **Selectivity:** Better ability to filter out noise from adjacent frequencies. * **Range:** Generally offers a longer and more stable communication range. ### Signal Processing The module converts incoming radio waves (RF) into digital pulses (TTL). It does not decode the data itself; it simply passes the pulses to a decoder IC (like the PT2272) or a microcontroller (MCU) for software decoding. --- ## 4. Typical Application Circuit When connecting this to a microcontroller, the setup is straightforward: ```c // Example: Basic pin definition for Arduino const int rxPin = 2; // Connect AK-AV100-R DATA pin to D2 void setup() { pinMode(rxPin, INPUT); Serial.begin(9600); } void loop() { int sensorValue = digitalRead(rxPin); // Process the incoming pulse train... } ``` --- ## 5. Usage Considerations * **Antenna:** The performance is highly dependent on the antenna. A straight copper wire or a spring antenna is required for optimal range. * **Noise:** Because it is an ASK receiver, it can be sensitive to electromagnetic interference (EMI) from motors or poorly shielded power supplies. * **Encoding Compatibility:** It works best with encoders like **EV1527** or **PT2262**.
