Various embodiments disclose an electronic circuit for an electrochemical gas sensor. The electronic circuit comprises a first switching element electrically coupled to a reference terminal of the electrochemical gas sensor and a ground voltage terminal. Further, the electronic circuit comprises a second switching element electrically coupled to a sensing terminal of the electrochemical gas sensor and the ground voltage terminal. In an instance in which the electrochemical gas sensor is powered OFF, the first switching element and the second switching element are configured to electrically couple the reference terminal and the sensing terminal to the ground voltage terminal such that current generated when the sensing electrode and the target gas react while the electrochemical gas sensor is powered OFF flows to the ground voltage terminal and the potential of the reference terminal and the sensing terminal remain the equal.

A system can receive an identifier for a query used by a query service of one or more query services and an identifier for the query used by an issuing computer system. The query service and the computer system that issued the query can use different schemas for query results. A mapping can be established that maps elements of one schema to the other schema. This mapping, and a mapping of the query identifiers, can be used to convert query results to a format useable by the computing system that issued the query. By converting query results from multiple query services, which may have different formats, to a common format of the issuing computing system, the use of multiple query services is facilitated.
