USB to 4Ch Serial RS485 Converter Cellular Antenna The XL‑MaxSonar-WR sensors are factory

The XL‑MaxSonar-WR sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long range detection zones

It is just two conductors with a fixed surface area at a fixed distance from each other

to realize hydrology and water resources data acquisition

please add the following boot-up script to read the stats (CPU/Memory load

and harsh environments such as high UV exposure

USB to 4Ch Serial RS485 Converter Cellular Antenna The XL‑MaxSonar-WR sensors are factoryUSB to 4Ch Serial RS485 Converter Features: Extending USB to 4CH RS485, allows concurrent and independent communication for each channel Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti electrostatic Onboard resettable fuse and protection diodes, ensures the current voltage stable outputs, provides over current over voltage proof, improves shock proof
