Keywords:SDI-12;Communication protocol;Program design;Methods;STC12 0引言 从SDI-12串行数据通信接口标准(以下统称SDI-12协议)诞生到现在已有二十多年时间,该协议在美国和欧盟使用较为广泛,主要用于江河湖海的水文和气象等地球环境监测、工农业多参数远距离测控等[1]。在我国,SDI-12协议也逐渐被熟知和应用。早在...
The SQ-521 is a digital sensor with SDI-12 communication protocol. The sensor incorporates a rugged, self-cleaning sensor housing design, anodized aluminum body with acrylic diffuser, and high-quality cable terminating in pre-tinned pigtail leads for easy connection to dataloggers and controllers....
Taking STC12LE5A60S2 as the core control unit, the sensor interface circuit and serial port transmission circuit are designed, the timing requirements of SDI-12 interrupt wake-up and retry are analyzed, and the specifi c methods to realize the SDI-12 communication protocol are analyzed, and ...
for RAK4631 and RAK1330. This library is used for SDI-12 communication with various environmental sensors. It provides a general software solution, without requiring any additional hardware, to implement the SDI-12 communication protocol between an Arduino-based data logger and SDI-12-enabled ...
The full communication protocol (for the data recorder) is explained below: data recorder sends a break by setting the data line to spacing (5 V) for at least 12 ms. The sensor will never recognise a break less than 6.5 ms and will always recognise one greater than 12 ms. ...
A: Common power supply and signal output is DC3.6-16V, SDI-12. But we can customize for you as demands.Q: How can I collect data? A: If you have your own data logger, you only need to buy our sensor and meanwhile we sen...
