Active Rfid

RFID is a non-contact automatic identification method, it can identify aim object automatically and obtain some correlative information by using RF signal. It doesn't require any manual intervention. It can be applied to various harsh environments. Combining active RFID technology and sensors, we develop a new product, i.e. HAC active RFID. Based on traditional active tags, it increases temperature monitoring. And it also realized the sensor, identification, and other wireless transmission in one whole, so that it greatly expands the traditional applications field of RFID technology. ======================================================================== Application: Logistics, including cargo tracking, automatic collecting information and storage management Manufacturing, used in the monitoring of data in the process of production and automated production Medical, used in the management of hospital equipment and patient identification. Food, used in the food processing, preservation and transportation monitoring 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 datas' 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 120m. . 5. Temperature measure Measure range: -20°C～60°C Precision of temperature: ±2°C 6. Battery voltage detection 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. ======================================================================== Specification: Time interval for transmitting: 10s Time tolerance: ±2s Transmitting power: 10mw Transmitting current: <35mA Visible transmission distance: >120m Sleep current: <1uA Working voltage: 3V DC Battery: CR2430 270mAh（two pieces） Measure range of temperature: -20°C～60°C Precision of temperature: ±2°C Continuous working time: more than four years Dimension： 45 *70 * 3.5mm
