Argmeter the open source laser power meter argmeter is an open source laser power meter platform for the arduino.
Arduino laser power meter.
I thought it l.
See the connection schematic below.
It can measure distance up to 125cm quite accurate.
This time of flight sensor is a laser distance sensor that emits a 940nm laser.
The tec will absorb the laser light and transform the heat generated by the laser beam to an electrical signal.
At this step you don t need to connect oled display to the arduino just connect tx line of the laser rangefinder module to the tx line of the arduino and power lines of the module to the 3v power source.
An operational amplifier is used then to amplify the signal and ouput it to a volt meter.
Https www hackster io iliasam making a cheap laser rangefinder for arduino 4dd849 this video describes how to load my custom firmware to the x 40 laser t.
Open the laser laser a single measurement gets to the power supply voltage and temperature.
The biggest surprise came when i pointed the laser module onto the lab s power meter.
Firstly you need to check that rangefinder module is working well.
Play video i belong to a village of odisha india where frequent power cut is very common.
Only 2 of the corners should come into contact and you can use a small drop of superglue to affix these to keep the cover slip firmly in place.
I was walking through the hardware store the other day and i walked past an energy meter which clips onto your home s electricity mains and then provides you with information on your power consumption and cost estimates for the month.
Adafruit delivers a ready to use library and a functional example you should try.
During my childhood days continuing studies after dusk was a real challenge.
This project has been through many prototypes and many designs and is finally ready for release.
Send capital letters o to open the laser capital letters c to close the laser capital letters d for measuring distance capital letters s to view the module temperature and power supply.
Voltage meter will display the power in w unit of the laser beam you are testing.
This type of meter uses a thermoelectric cooling module tec to measure the power of a laser.
Wiring up the shield in the arduino enclosure and using a bnc connector and also soldering the laser to a bnc connector makes it easy to deploy the laser.
It hampers the life of every one.
Due to this problem i designed a solar syste.
How to use your laser power meter.
The laser module has a m10 0 5 thread so i ordered a thorlabs sm1 to m10 0 5 adapter.
