Cars, traffic and many other industries
1. Ultra low power transmission
The maximum transmission is 10mw.
2. ISM frequency band with no require of applying frequency
The carrier frequency is 433.516MHz, it is a fixed frequency. The other frequencies are available if needed. If you need to choose setting channel, you should customize the products in quantity.
3. High anti-interference and Low BER (Bit error Rate)
Based on the Minimum Shift Keying (MSK) modulation, the high-efficiency forward error correction channel encoding technology is used to enhance data’s resistance to both transient interference and random interference.
4. Long Transmission Distance
Within the visible range, the reliable transmission distance of PCB antenna is more than
5. Temperature measure
Measure range:
Precision of temperature: ±
6.
Detect the state of battery voltage in RFID, so that you can change the battery in time.
7. RSSI signal query
RSSI signal is Received Signal Strength Indication. According to the signal, you can know the effect of receiving at that time, or the distance.
8. Low power consumption
The receiving current is less than 35mA, and the sleeping current is less than 1uA. It is low power consumption, so that it is much better for the environment.
According to one transmission every 10 seconds, and transmitting time is 2ms. The total electric quantity of two batteries is 540mAh. The continuous working time is calculated as follows:
The average current consumption of one transmission: 35mA * 0.002s/10s = 0.007mA
The total consumption of average current: 0.007mA + 0.001mA = 0.008mA
The theoretical value of time for battery: 540mAh/0.008mA = 67500h = 7.7 years
Actually, you only can use 60% electric quantity of battery, so the actual battery life is up to four years.
9. High reliability, small and light
By using monolithic radio-frequency integrated circuit and single-chip MCU, the transceivers have less peripheral circuits, higher reliability, and lower failure rate.
