When the voltage is greater than 12V, the power consumption increases and the effective transmitting power does not increase significantly. The RF module
ET-RX-13 is characterized by large transmission power and long transmission distance, which is suitable for communication under harsh conditions. Antenna had better choose 25 cm long wire, long distance transmission had better be able to stand up, because of the influence of many factors when radio signal transmission, so the general practical distance is only half or even less than the nominal distance, this need to pay attention to development. RF module
ET-RX-13 adopts ASK mode modulation to reduce power consumption. When the data signal stops, the transmitting current drops to zero, and the data signal can be directly connected with the input end of the transmitting module by resistance or capacitance coupling, otherwise the transmitting module will not work properly. The data level should be close to the actual operating voltage of the data module to obtain higher modulation effect.
