Project description
I needed a way of remotely monitoring the temperature and relative humidity in a greenhouse used by my local garden club. We grow and graft tomato plants for our annual plant sale. Careful control of the T and RH is helpful to insuring the success of the grafting process. Given the large T and RH changes that a greenhouse can experience it is useful to measure the conditions 24 hours a day, seven days a week for analysis. After exploring commercial recording hygrothermographs and determining the cost to be prohibitive I decided to build my own. The basic design specs for this device were to…
