The goal of this project is to give hobbyists access to a diy lpm design for only the cost of hardware that they can expand and modify to suit their needs.
Arduino laser power meter.
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.
Firstly you need to check that rangefinder module is working well.
Argmeter the open source laser power meter argmeter is an open source laser power meter platform for the arduino.
Adafruit delivers a ready to use library and a functional example you should try.
How to use your laser power meter.
I thought it l.
Open the laser laser a single measurement gets to the power supply voltage and temperature.
The laser module has a m10 0 5 thread so i ordered a thorlabs sm1 to m10 0 5 adapter.
It can measure distance up to 125cm quite accurate.
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.
Simple arduino home energy meter.
It hampers the life of every one.
During my childhood days continuing studies after dusk was a real challenge.
Due to this problem i designed a solar syste.
Play video i belong to a village of odisha india where frequent power cut is very common.
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.
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.
This type of meter uses a thermoelectric cooling module tec to measure the power of a laser.
The tec will absorb the laser light and transform the heat generated by the laser beam to an electrical signal.
This project has been through many prototypes and many designs and is finally ready for release.
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.
Voltage meter will display the power in w unit of the laser beam you are testing.
An operational amplifier is used then to amplify the signal and ouput it to a volt meter.
When your laser target has completely dried for a minimum of 24 hours put the glass slip into a 33mm slide holder or a cardboard holder fashioned in a similar manner.
See the connection schematic below.
