COVID-19 IMPACT

Temperature Transmitter and Humidity Transmitter Market Had a Negative Effect Due to Supply Chain Disruption During COVID-19 Pandemic

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

The temperature transmitter and humidity transmitter market share were negatively affected by the COVID-19 pandemic because it caused global supply chains to become disrupted, industrial activity declined, and capital investments were postponed. Oil and gas, automotive, mining, and pulp and paper are just some of the end-user industries that were shut down and unable to operate at full capacity; as a result, demand on process automation equipment was decreased temporarily. Factories in Asia, North America and Europe reported workforce losses and raw material warehouse delays, which had additional impact on the production and delivery dates of transmitters. Also, the resource constraint in the crisis compelled most industries to focus on cost reduction rather than modernization programs reducing the rate of uptake of the new sensor technologies. HVAC installations and building automation projects which often require humidity transmitters were also hit by the construction slow down. Although healthcare and pharmaceutical industries offered certain protection through higher demand on controlled environments, it was not enough to compensate the total losses. Moreover, trade limitations and delays in transportation caused backlog affecting manufacturers in terms of revenue. Nevertheless, the pandemic also put the issues of automation, remote monitoring, and energy-efficient systems into the limelight, and these will lead to the renewed growth in the post-pandemic age.
