Showing PPM value on Hardware with Arduino and MQ-137: Enough of all the theory let us build a simple circuit with the sensor and LCD to display the value of gas in PPM. Here the sensor I am using is MQ137 which measures ammonia, the circuit diagram for my set up is shown below.

The NSI low-level monitor senses CO levels as low as 5 ppm (parts per million). Infants, children, elderly, people with respiratory or heart ailments are provided little or no protection from deadly CO with standard alarms. Long-term exposure to low-level CO above 15 ppm can cause illness and even permanent disabilities. PPM Cadereyta, Cadereyta De Jiménez, Nuevo Leon, Mexico. 55 likes.

A concentration of 34 to 51 ppm has been reported to be lethal in 1 to 1.5 hours [Freitag 1941] while 14 to 21 ppm has been suggested as being dangerous within 0.5 to 1 hour [NPIRI 1983]. Revised IDLH: 10 ppm The concentration C in parts-per million (ppm) is equal to 1000 times the concentration C in grams per kilogram (g/kg) and equal to 1000000 times the concentration C in grams per liter (g/L), divided by the solution density ρ in kilograms per cubic meter (kg/m 3): DWC Reservoir ppm is too high/low: Too high: Add plain ph’d water to the reservoir and test. Repeat until your reservoir reaches a safe fill point, or the ppm is in the correct range. If the ppm is still too high, you can wait for the plant to lower the water levels, or you can change the reservoir water altogether. I am feeding 350-400ppm and growing in coco.

PPM (Parts per million) is a measurement used by many customers to measure quality performance. Definition: One PPM means one (defect or event) in a million or 1/1,000,000 In the past a good supplier would have a defect rate of less than 1%, (10,000 PPM).

Parts per million are found in most types of water, from tap water to mountain spring water. ppm is an abbreviation of parts per million. ppm is a value that represents the part of a whole number in units of 1/1000000.
