A microfluidic sensor includes a microchannel that includes a reaction site with a reagent and a sample inlet. A liquid substance is received at the sample inlet and travels by capillary action to the reaction site. A temperature sensor measures a temperature as a result of a reaction between the reagent and a chemical in the liquid substance. A controller is communicatively connected to the temperature sensor, receives the temperature measured by the temperature sensor, and derives a concentration of the chemical in the liquid substance from the temperature.
