ITEM NAME:New 433MHz High Sensitivity Decoding Superheterodyne Receiving Module Product Description Description: Feature: 100% new and high quality Easy and convenient to operate Energy-saving design, allows long service life Stable performance, small size and high receiver sensitivity Your best choice for a more convenient daily life Compatible with the long distance wireless remote control switch, different kinds of anti-lost alarm system, the remote control of household appliances and intelligent toys, wireless sensor, wireless meter reading, industrial control and security surveillance etc. Description: Weight: 50g Working voltage: DC 12V Operating frequency: 433MHz Low power consumption: 4.7mA(433MHz, in full operation) Sensitivity: -110dBm(433MHz) Transmission rate: 2.5kbps(FIXED), 10kbps(SWP) Output level: TTL Operating temperature: -20℃ ~ +60℃ Modulation method: ASK Working principle: Superheterodyne Size: 26*12*6.5mm Length of antenna: 18cm(433MHz) Note: 1. Connecting the DC power supply correctly, and the voltage of power supply  must be between the scope of working voltage. 2. The position of antenna also has an effect on receiving module, so you can make the antenna directly welded the ANT interface, you can also receive after connecting to the module through the ANT system of pin. As for the installation, the antenna should be straight and perpendicular to the ground, away from the areas of shield, high pressure and interference. 3. Used with the host, you must must consider whether the host will cause interference to ZW21-J. Included: 1 x Module.Working principle: Superheterodyne. Low power consumption: 4.7mA(433MHz, in full operation). Sensitivity: -110dBm(433MHz). Length of antenna: 18cm(433MHz). The position of antenna also has an effect on receiving module, so you can make the antenna directly welded the ANT interface, you can also receive after connecting to the module through the ANT system of pin.
