Serial.println("Filesystem datalogger\n"); } [Get Code] 在loop()里,创建一个字符串来伴随着timestamp开始,或者安排记录数据。下面将创建getTimeStamp()函数。 void loop () { String dataString; dataString += getTimeStamp(); dataString += " = "; [Get Code] 从传感器里读取数据,并加在字符串...
Once we are able to connect with the SensorTag and read the sensors with the Arduino 101, we need to be able to save the data. Additionally, because we will be logging the data periodically, we need to timestamp the sensor readings. To accomplish these functions, the third and final hard...
I found the GPS unit was able to get a fix on the satellites even inside my house. Overall I am very pleased with this hardware. I will be exploring a bit with this hardware and learning more about the software. The ultimate goal is to have GPS hardware to collect data for the Truck...

This data logger lets you save data to files on any FAT16- or FAT32-formatted SD card easily from an Arduino, which can then be read by most plotting, spreadsheet, or analysis programs. The onboard real time clock (RTC) timestamps all your data with the current time, so that you ...
The included Real Time Clock timestamps all your data with the current time, so that you know precisely what happened when! Please note that this item does not come with an for Arduino NANO (you'll need one to use with the shield), or an SD card. It doesn't come with the RTC bat...
Records can also be located using Timestamp in logarithmic time by doing a Binary Search on the data logged. This is not possible using conventional loggers. For example, locating any record in a 70 MB db having 1 million records on Arduino UNO with SparkFun microSD Shield took only 1.6 ...

(Therefore 2 way communication :)) Timestamped datalogger is the next iteration. Reply Mitch January 30, 2020 at 7:08 pm I tested ESP NOW with this example and it is very impressive. In my distance tests from outdoors, through two walls to the receiver indoors, I was able to get ...
The SD library has a simple Datalogger example. Unlike a professional datalogger, this one does not use a real time clock to add a timestamp to the data, it simply reads the data and writes it to a file on the SD card. To use this sketch you will need to add some additional comp...
