Temperature and humidity control of the intelligent greenhouse is an important link of monitoring. This paper uses Surplus 16-bit single chip microcomputer as the core control of the system. Combined with wireless transceiver chip NRF401, USB interface device PDIUSBD12 and temperature and humidity module YXHT300U, we designed a wireless temperature and humidity monitoring system which used in intelligent...
In the remote, hazardous, distributed and external environment, such as radiation source, pollutant source and pipeline of petrol, water and gas, it is difficult to collect and send the necessary message in real-time by traditional monitoring ways. In response to this demand, this paper presents the design of wireless remote monitoring system solution that is based on the GPRS(General Packet Radio...
Ultrasonic detection is widely used in the area of non-destructive testing system of wood intensity. In this paper, after analyzing the principle of the ultrasonic detection method of the wood modulus of elasticity, we have proposed a scheme which is based on Texas Instrument's DSP (Digital Signal Processor) TMS320LF2407. This DSP provides an efficient solution to computational complexities of the...
