Please set the appropriate fine dust management standards in T2PM. The T2PM, equipped with a laser scattering type fine dust sensor, measures PM2.5 as standard and measures fine dust of various sizes from PM0.5 to PM10.0. The measurement method can also be selected as a desired type from among the cumulative type and the range range type.

All data measured by the RN400 is stored in F-RAM. F-RAM is a non-volatile memory whose contents are not erased even without power. It is 100 times faster than general flash memory and has very high write endurance. Measured data is stored in F-RAM, and the data is transmitted to the location desired by the user every transmission cycle. Even when Wi-Fi is disconnected, data is still saved, so monitor with confidence.

RN400 was requested by multinational corporations for high-grade Wi-Fi functions from the time of planning. The RN400 is therefore implemented to support enterprise security. This is a function that is not commonly used in home wireless routers, and is often used by businesses that require a high level of security. In order to use Wi-Fi in the Wi-Fi Enterprise security level, you can register not only the Wi-Fi password but also a separate ID/PASSWORD to the computer team and use it after receiving a usable certificate from the computer team.

Industrial sites in various environments exist. We have launched the RN400 product with waterproof specifications by reflecting the requirements of various fields such as meat processing companies that clean with water or pharmaceutical/bio that disinfects chemicals. With an IP65 rating, the outer housing is finished with a gasket, and the input/output part of the sensor is treated with a cable gland.

Since the RN400 uses a battery for Wi-Fi communication, the battery consumption must be well designed. It does not consume the battery when it is not in the measurement cycle, and uses the battery only for measurement/transmission. DC power supply is also available. At this time, the BUILT-IN UPS function is implemented in a circuit so that the built-in battery can act as an auxiliary power immediately in the event of a power outage. Even if there is a power outage, the data collection function is performed normally.
