OPS243 Radar Sensor OmniPreSenses OPS243 is complete short-range radar (SRR) solution providing motion detection, speed, direction, and range reporting. All radar signal processing is done on board and a simple API reports the processed data. Flexible control over the reporting format, sample rate, and module power level is provided. The OPS243 carries FCC/IC modular approval, simplifying development and regulatory certifications for production release. The OPS243 sensor outputs data over USB, UART, or RS-232 interface for simple connection to Arduino, OPS243 Sensor Raspberry Pi, PC, or any embedded processor. Features 1-100m (3-328) detection range Speed reporting up to 348mph Direction reporting (Inbound/Outbound) Range reporting up to 60m (197) Simple object counting mode OPS243 Detection Range Narrow 20 beam width (-3 dB) Simple, flexible API 0 352 8 344 16 25.0 336 24 USB, UART, and RS-232 interface 328 32 20.0 320 40 15.0 312 48 FCC/IC modular approval 10.0 304 56 5.0 296 64 Industrial temp operation (-40 to +85 C) 0.0 288 72 -5.0 1.7W Active or <0.2W Hibernate power 280 80 -10.0 272 88 -15.0 Smaller form factor 75 x 90 x 12 mm, 15g 264 96 256 104 248 112 Applications 240 120 232 128 224 136 Smart City 216 144 208 152 200 160 192 168 Robotics/Drones 184 176 Functionality Antenna Pattern Part Number Motion Direction Speed Range Traffic Monitoring OPS243-A Presence Detection OPS243-C Speed/Direction Reporting www.omnipresense.com OPS-PB-004-C OmniPreSense Corporation 1650 Zanker Road, Suite 222 San Jose, CA 95112 OPS243 Radar Sensor Electrical Specifications Parameter Value Notes Operating Frequency 24.00-24.25GHz ISM band Transmit Power 11 dBm Transmit Antenna Azimuth 20 -3 dB beamwidth Transmit Antenna Altitude 24 -3 dB beamwidth 1.7W (typ) Active power, OPS243-C Power Dissipation 0.7W (typ) Idle power 0.2W (avg) Hibernate, OPS243-C UART Pin Signal Level 3.3V RS-232 Pin Signal Level 5V 24V for sensors built after Supply Voltage 5-24V July 2020, otherwise 13.5V Operating Temperature -40 to +85C Ordering Information Sensor Type Interface Ordering Part Number OPS243-A Doppler USB, UART OPS243-A-CW-RP OPS243-A Doppler USB, RS-232 OPS243-A-CW-R2 OPS243-C Doppler & FMCW USB, UART OPS243-C-FC-RP OPS243-C Doppler & FMCW USB, RS-232 OPS243-C-FC-R2 Enclosure - - OPS243-A-CW-ENC www.omnipresense.com OPS-PB-004-C OmniPreSense Corporation 1650 Zanker Road, Suite 222 San Jose, CA 95112
