Arduino Laser Power Meter

This project has been through many prototypes and many designs and is finally ready for release.

Arduino laser power meter.

This time of flight sensor is a laser distance sensor that emits a 940nm laser. The laser module has a m10 0 5 thread so i ordered a thorlabs sm1 to m10 0 5 adapter. During my childhood days continuing studies after dusk was a real challenge. An operational amplifier is used then to amplify the signal and ouput it to a volt meter.

See the connection schematic below. 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. Due to this problem i designed a solar syste. Simple arduino home energy meter.

Open the laser laser a single measurement gets to the power supply voltage and temperature. It can measure distance up to 125cm quite accurate. Adafruit delivers a ready to use library and a functional example you should try. 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.

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. 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. 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. 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.

I thought it l. 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. How to use your laser power meter. The tec will absorb the laser light and transform the heat generated by the laser beam to an electrical signal.

It hampers the life of every one. Voltage meter will display the power in w unit of the laser beam you are testing. Firstly you need to check that rangefinder module is working well. 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.
