MicroAmp-Meter which is a current measurement tool featuring auto-ranging, Wi-Fi current profiling, SD card logging options, and more. It is a portable current meter that can record and profile the current consumption of devices in real time.
MicroAmp-Meter is a portable current meter that can record and profile the current consumption of IoT devices in real-time. Typical multimeters have an analog switch for different current ranges that make it difficult to measure the current consumption of devices, having a wide dynamic range of current levels e.g. ESP32 consumes about 240mA in active mode and 10uA in deep sleep mode. MicroAmp-Meter provides a solution to the problem as it has an automatic shunt-switching mechanism that enables it to measure the dynamic range of current levels ranging from 1uA to 1Amp. It has inbuilt WiFi and an application that provides a real-time graphical representation of the current in a web browser. It can also log current and other parameters on a Micro SD card for more than 12 hours.
Wi-Fi Mode
Wi-Fi mode is the main feature of the MicroAmo-Meter that provides an application to visualize current readings and other parameters over the web browser at a high speed of 4000 samples/second. The webpage application code resides inside the memory of MicroAmo-Meter. MicroAmp-Meter and web browser both need to be connected to the same Wi-Fi network. No internet connection or installation of software is required.
SD Card Logging Mode
SD card logging feature is useful to measure the current performance of a device over a long run. This feature logs the following parameters in the SD card over a time interval of 1 second:
- Average current
- mAh (milliampere/hour)
- Voltage
Project is set to launch on crowdfunding campaign at Kickstarter. For all features and information visit www.danalogx.com
